Objective— To report a technique for tube cystostomy placement via a minimally invasive inguinal approach and outcome in 9 dogs and 6 cats with urinary tract obstruction or detrusor atony.
Study Design— Case series.
Animals— Dogs (n=9) and cats (6).
Methods— Medical records (January 2004–January 2008) of dogs and cats that had tube cystostomy via an inguinal approach were reviewed. Retrieved data included signalment, diagnosis, surgical technique, and complications. Access to the bladder was through a muscle splitting approach in the inguinal region with the cystostomy tube placed through a skin incision made several centimeters proximal to this incision and secured in the bladder by a purse string suture. Cystopexy during closure of the muscle layers ensured secure closure and minimized the likelihood of uroabdomen if tube dislodgment occurred.
Results— Cystostomy tubes were placed in 5 cats as an emergency procedure for treatment of acute urinary tract obstruction or urethral rupture, and as an elective procedure in 9 dogs and 1 cat. No complications occurred during cystostomy tube placement. Postprocedural complications were minor (peristomal irritation in 2 dogs with latex catheters, catheter laceration, premature removal) and only occurred when tubes were retained for >4 weeks. Urinary tract infection at catheter removal in 6 dogs resolved with antibiotic administration.
Conclusions— An inguinal approach for cystostomy tube placement facilitated rapid catheter placement into the bladder with minimal soft tissue dissection. Cystopexy during abdominal wall closure provided peritoneal protection should premature dislodgement of the cystostomy tube occur.
Clinical Relevance— An inguinal approach should be considered for rapid tube cystostomy particularly in metabolically compromised animals.  相似文献

Traditional cystostomy tubes (used for temporary or permanent diversion of urine in dogs and cats) are long (> or = 22 cm) and cumbersome to stabilize, requiring sutures or bandages to hold the tube against the body. Use of a low-profile gastrostomy port system as a low-profile cystostomy tube (LPCT) in 4 dogs and a cat was investigated; owner satisfaction with the device was assessed. Technical difficulty associated with placement and management of LPCTs was similar to that for traditional cystostomy tubes; with LPCTs, activity and mobility of pets was not compromised, and bandaging was not required. Complications included lower urinary tract infection, mild peristomal leakage of urine and leakage from components of the system, and subcutaneous peristomal infection. Four of 5 owners considered the tube to be easy to use; all owners said they would be comfortable repeating their decision to use the LPCT in their pet.  相似文献

OBJECTIVE: To identify clinical features of Corynebacterium urealyticum urinary tract infection in dogs and cats and antimicrobial susceptibility patterns of C urealyticum isolates. DESIGN: Retrospective study. ANIMALS: 5 dogs and 2 cats. PROCEDURE: Medical records of dogs and cats for which C urealyticum was isolated from urine samples were reviewed. Isolates from clinical cases, along with previously lyophilized unsubtyped isolates of Corynebacterium spp collected between 1977 and 1995, were examined and, if subtyped as C urealyticum, tested for antimicrobial susceptibility. RESULTS: Signalment of infected animals was variable. Prior micturition disorders were common, and all animals had signs of lower urinary tract disease at the time C urealyticum infection was diagnosed. Median urine pH was 8.0; WBCs and bacteria were variably seen in urine sediment. In vitro antimicrobial susceptibility testing of 14 C urealyticum isolates revealed that all were susceptible or had intermediate susceptibility to chloramphenicol, tetracycline, and vancomycin and most were susceptible to enrofloxacin. Thickening of the bladder wall and accumulation of sediment were common ultrasonographic findings. Contrast radiography or cystoscopy revealed findings consistent with encrusting cystitis in 3 dogs. Infection resolved in 2 dogs following surgical debridement of bladder plaques and antimicrobial administration. In 2 other dogs and 1 cat treated with antimicrobials, infection with C urealyticum resolved, but urinary tract infection with a different bacterial species developed. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that preexisting urinary tract disorders are common in dogs and cats with C urealyticum infection. Treatment with appropriate antimicrobials in combination with surgical debridement might eliminate C urealyticum infection.  相似文献

OBJECTIVES: To determine the requirement for 2nd surgical interventions and mortality after 3 different surgical techniques (percutaneous tube cystostomy [10 goats], surgical tube cystostomy [25 goats], urinary bladder marsupialization [10 goats]) for caprine obstructive urolithiasis, and to determine whether pre- or 24-hour postoperative physical examination findings or serum chemistry results could be used as predictors of mortality. STUDY DESIGN: Retrospective study. ANIMALS: Male goats (45) with obstructive urolithiasis. METHODS: Medical records for all male goats admitted and operated for obstructive urolithiasis between 1993 and 2003 were reviewed. Data retrieved included signalment, pre- and 24-hour postoperative values for temperature, pulse, respiratory rate, packed cell volume, serum K(+), serum creatinine, and blood urea nitrogen [BUN]. The type of initial surgical procedure, time to 2nd surgical intervention, time to death, and duration and cost of hospitalization were also obtained. RESULTS: Percutaneous tube cystostomy was associated with a significantly increased requirement for (5.6-fold increased hazard) and decreased time to a 2nd intervention (P=.002). There were no differences between the 3 procedures for time to mortality. Increased BUN and respiratory rate at admission were associated with increased mortality (hazards ratio of 4.8 and 5.0, respectively). Urinary bladder marsupialization was associated with significantly decreased hospitalization time (P=.02) and cost (P=.04) compared with surgical tube cystostomy and percutaneous tube cystostomy. CONCLUSION: Surgical tube cystostomy and bladder marsupialization are both acceptable surgical methods for treatment of caprine obstructive urolithiasis. Each procedure has inherent complications that should be discussed with the owner before choosing the surgical treatment. CLINICAL RELEVANCE: There are acceptable options for treatment of caprine obstructive urolithiasis; however, percutaneous tube cystostomy should be avoided.  相似文献

OBJECTIVE: To investigate the feasibility and long-term outcome of a modified subpubic urethrostomy technique termed transpelvic urethrostomy (TPU) in cats. STUDY DESIGN: Prospective clinical study. ANIMALS: Eleven male cats with obstructive lower urinary tract disease that could not be relieved, and requiring a surgical urinary diversion, were selected for TPU. METHODS: With the cat in dorsal recumbency, the penis was exposed and the ventral pelvis was denuded by median adductor muscle elevation. An approximately 12 mm x 15 mm area of ischium was removed. The pelvic urethra, 8-20 mm cranial to the bulbourethral glands, was incised longitudinally and sutured to the skin to create a urethrostomy. RESULTS: All cats were neutered males (2-9 years); none were uremic or hyperkalemic at admission. Urine was cultured if there was leukocyturia, nitrituria, and/or bacteriua. Bacteria were isolated from 2 specimens. A patent urethrostomy was created in all cats without operative complications. Except for 1 cat without associated clinical signs, stricture was not evident between 9 and 42 months after urethrostomy. One cat had postoperative urinary incontinence (UI) that resolved within 4 weeks. Two cats each had 1 episode of idiopathic lower urinary tract disease after 6-month follow-up; both responded to medical therapy. CONCLUSIONS: TPU was used as a successful urinary diversion procedure relieving signs of urinary tract obstruction and preventing further obstruction, with few complications. The incidence of UI after TPU remains minimal. CLINICAL RELEVANCE: TPU should be considered as a salvage urinary diversion procedure in cats (as an alternative to prepubic and subpubic techniques). TPU may also be considered as a possible primary urinary diversion solution (an alternative to perineal urethrostomy) for obstructive lower urinary tract disease in cats.  相似文献

Adrenal neoplasia is a common problem in middle-aged to older ferrets. Male ferrets may present for stranguria and dysuria due to prostatic/paraurethral tissue enlargement secondary to elevation in androgens produced by the neoplastic tissue. Progressive urethral compression followed by complete urinary obstruction can result. Urinary obstruction can persist for days following surgery requiring urinary diversion. Four ferrets presenting with signs consistent with urinary obstruction secondary to adrenal disease were immediately treated with urethral catheterization or cystocentesis followed by adrenalectomy and temporary tube cystostomy. The tube cystostomy placement and use were associated with minimal complications and allowed recovery from surgery.  相似文献

OBJECTIVES: Lateral thoracotomy is widely used for surgical management of thoracic diseases in small animals. The purpose of this paper is to describe the indications for lateral thoracotomy in dogs and cats and the associated outcomes and complications. METHODS: Medical records of animals undergoing lateral thoracotomy were reviewed and owners contacted regarding complications and survival. Relationships between signalment and treatment variables and outcome variables were investigated. RESULTS: Seventy dogs and 13 cats underwent lateral thoracotomy. Sixty-two per cent of cats and 91 per cent of dogs survived to discharge. Survival to discharge was significantly lower in cats than dogs, for neoplastic than non-neoplastic disease and in older animals. Survival to discharge was higher in animals undergoing patent ductus arteriosus ligation than in those undergoing lung lobectomy or oesophageal surgery. Survival to discharge was not related to surgeon experience. The incidence of complications was not related to species, age, disease, duration of surgery, surgeon experience or duration of thoracostomy tube placement. A low complication rate (5 per cent) was associated with thoracostomy tubes. CLINICAL SIGNIFICANCE: The approach of lateral thoracotomy has a minimal complication rate and animals with a disease requiring this approach have a high survival rate.  相似文献

Feeding commercial enteral diets to critically ill dogs and cats via nasogastric tubes was an appropriate means for providing nutritional support and was associated with few complications. Twenty-six cats and 25 dogs in the intensive care unit of our teaching hospital were evaluated for malnutrition and identified as candidates for nutritional support via nasogastric tube. Four commercial liquid formula diets and one protein supplement designed for use in human beings were fed to the dogs and cats. Outcome variables used to assess efficacy and safety of nutritional support were return to voluntary food intake, maintenance of body weight to within 10% of admission weight, and complications associated with feeding liquid diets. Sixty-three percent of animals experienced no complications with enteral feedings; resumption of food intake began for most animals (52%) while they were still in the hospital. Weight was maintained in 61% of the animals (16 of 26 cats and 15 of 25 dogs). Complications that did occur included vomiting, diarrhea, and inadvertent tube removal. Most problems were resolved by changing the diet or adhering to the recommended feeding protocol. Nutritional support as a component of therapy in small animals often is initiated late in the course of the disease when animals have not recovered as quickly as expected. If begun before the animal becomes nutrient depleted, enteral feeding may better support the animal and avoid serious complications.  相似文献

Tube cystostomy was used to treat 13 goats and two sheep with obstructive urolithiasis. The cystostomy tube was intermittently occluded 3 to 4 days after placement to determine if urine could be voided through the urethra. If the animal showed no discomfort during urination after the cystostomy tube had been occluded for several days, the tube was removed. This procedure was successful in relieving urethral obstruction in 12 animals. The mean time until the animal could urinate freely and until the cystostomy tube was removed was 11.5 and 14.4 days respectively. Follow-up was available for 10 animals; seven were alive with no recurrence of urinary obstruction. One goat died from causes unrelated to urinary obstruction 1 year postoperatively. One goat died from unknown causes, and one goat died after urinary obstruction recurred.  相似文献

Percutaneous gastrostomy tubes were placed non-endoscopically in 31 cats and 10 dogs using either a rigid insertion tube (n=13) or an Eld gastrostomy tube applicator (n=28). Tubes were placed successfully in 38 of the 41 animals and the consequent feeding was of therapeutic benefit to 31 of the animals. Six of 41 died or were euthanased for reasons unrelated to gastrostomy. In four cases (10 per cent), gastrostomy failed with respect to correct tube placement or tube feeding. Overall complications occurred in 18 of 41 animals. Severe procedural complications occurred in two cats; a cardiorespiratory arrest during pharyngeal manipulation and erroneous tube placement through the distal oesophagus. Moderate late complications included peristomal food leakage (n=2), peristomal abscess (n=2) and pyloric outflow obstruction by a migrated tube (n=1). Complications associated with the feeding procedure, nausea and vomiting (n=3), led to aspiration pneumonia in one case.  相似文献

Prepubic tube cystostomy was performed in 10 dogs and one cat. Indications include urinary bypass following urethral trauma or surgery (six cases), following surgery for prostatic abscesses or cysts (four cases) and bladder atony secondary to urethral obstruction (one case). Tubes were left in situ for a minimum of seven days. All patients returned to normal micturition following tube removal. Urine leakage occurred for up to four days after tube removal by which time the stoma was granulating. Nosocomial infection was a consistent finding, but was controlled with antibiotic treatment following tube removal. Tube cystostomy was considered an effective means for diverting irritant urine from healing epithelium and thereby minimising the risk of urethral cicatrisation. It may also be indicated in the management of urinary retention as an alternative to repeated urethral catheterisation. This study indicates that tube cystostomy is readily performed, with few unexpected or serious complications.  相似文献

OBJECTIVE: To investigate the indications for and long-term outcome of prepubic urethrostomy (PPU) in the cat. STUDY DESIGN: Retrospective survey. ANIMALS: Sixteen cats that had undergone PPU. METHODS: Data were recovered from the medical records of the cats. Follow-up information was obtained from the owners and referring veterinarians. RESULTS: Indications for PPU were: failed perineal urethrostomy for the management of idiopathic lower urinary tract disease (ILUTD) (8 cats) or urethral trauma (1 cat); unresolved pelvic urethral obstruction after recurrent ILUTD (5 cats); and stenosis of the pelvic urethra as a result of trauma (2 cats). A patent urethral stoma was created in all cases. Signs of lower urinary tract disease were present in 8 cats postoperatively. With appropriate dietary management, these signs resolved in 2 cats and improved in another 4 cats. Eleven cats experienced postoperative complications that consisted of peristomal skin irritation or necrosis (7 cats) and urinary incontinence (6 cats). Complications developed in the immediate postoperative period in 6 cats, and resolved in 2 of these. Six cats developed late complications, at 6 to 84 months postoperatively. Six cats were euthanatized between 1 and 26 months' postoperatively. The mean survival time in these cats was 13 months. Reasons for euthanasia included urinary incontinence (3 cats), skin necrosis (2 cats), and unresolvable ILUTD (1 cat). CONCLUSIONS: PPU is a salvage procedure that is successful in relieving the signs of urinary tract obstruction and preventing further obstruction. However, potential complications should limit its use to cases in which standard techniques for perineal urethrostomy cannot be performed. CLINICAL RELEVANCE: PPU is a comparatively simple procedure that should be considered as a salvage technique for obstructive disease of the pelvic urethra.  相似文献

OBJECTIVE: To assess cystoscopic transurethral resection (TUR) for the palliative management of dogs with neoplastic infiltration of the urethra. STUDY DESIGN: Prospective clinical trial. ANIMALS: Six client-owned dogs. METHODS: Cystoscopic examination and electrosurgical TUR were performed in dogs with urination difficulties caused by prostatic or urethral neoplasia. TUR was performed in a retrograde manner in female dogs and antegrade in male dogs via exploratory celiotomy and ventral cystotomy. Cystoscopic examination was used to determine the extent of neoplastic involvement of the urethra. TUR involved piecemeal removal of neoplastic tissue from the urethral lumen using an electrocautery cutting loop. Hemorrhage was controlled with a cystoscopic cauterized roller-ball. In 2 male dogs, intraoperative radiation therapy (IORT) was used to treat both prostatic neoplasia and the sublumbar lymph node bed. Surgical technique, complications, adjuvant treatment, and outcome were recorded. RESULTS: TUR was performed in 3 male dogs with prostatic carcinoma and 2 female dogs with urethral transitional cell carcinoma (TCC). In 1 female dog, TUR was attempted but not successful because of cystoscope diameter. Iatrogenic urethral perforation occurred during TUR in 3 dogs. In 2 dogs, prolonged exposure to lavage fluid resulted in clinical and biochemical abnormalities consistent with TUR syndrome. Dysuria resolved in 5 dogs within 10 days of TUR. Treatment-related complications included urinary tract infection and tumor seeding. Local tumor progression and metastasis occurred in all dogs. CONCLUSIONS: TUR (in combination with chemotherapy+/-IORT) resulted in rapid palliation of urination difficulties in male dogs with prostatic carcinoma. In female dogs with urethral TCC, however, electrosurgical TUR cannot be recommended because of a high intra- and postoperative complication rate with no improvement in postoperative management compared with historical reports of tube cystostomy. CLINICAL RELEVANCE: TUR is a novel alternative for the palliation of male dogs with prostatic carcinoma. In female dogs with urethral TCC, electrosurgical TUR does not provide any advantages compared with tube cystostomy.  相似文献

OBJECTIVE: To evaluate outcome of small ruminants after tube cystostomy without urethral flushing. STUDY DESIGN: Retrospective clinical study. ANIMALS: Small ruminants (n=63; 50 goats, 13 sheep). METHODS: Medical records (January 1996-October 2003) for all small ruminants undergoing tube cystostomy were analyzed. Signalment, laboratory data, intraoperative findings, urolith type, and postoperative outcome were compared. Long-term follow-up was obtained at 6 and > or= 12 months postoperatively. RESULTS: Most animals were castrated males. Pygmy goats were overrepresented. Mean time to normal urination after tube cystostomy was 11 days, and mean hospitalization was 14 days. Seventy-six percent of animals were successfully treated with tube cystostomy (90% of those discharged from hospital). Short- and long-term survival was good for those animals with follow-up data. Reobstruction occurred in <20% of animals at 6 and 12 months. Goats, castrated males, and animals with normal serum potassium, no fluid in the abdomen, or no urethral process amputation were more likely to survive. Stone type, bladder appearance, and age at castration were not associated with outcome. CONCLUSION: Surgical tube cystostomy without urethral flushing is an effective technique for resolution of obstructive urolithiasis in small ruminants. CLINICAL RELEVANCE: Goats, small ruminants with an intact urethral process, absence of abdominal fluid, and serum potassium concentration <5.2 mEq/L at admission were all associated with survival after tube cystostomy. Castrated males may also be more likely to survive. These factors should be considered in management of small ruminants with urolithiasis.  相似文献

This report describes a cat that suffered pelvic urethral rupture associated with multiple pelvic fractures. A vaginourethroplasty was performed as a salvage procedure, via intrapelvic anastomosis of the proximal urethra to the caudal vagina, following failure of a primary urethral anastomosis. Urinary diversion was achieved via tube cystostomy and a vagino-urethral catheter was maintained for 3 days postoperatively. Anterograde cystourethrography was performed at 7 days and 14 days postoperatively. Absence of contrast leakage from the vagino-urethral anastomosis was documented at 14 days postoperatively and the tube cystostomy was removed. An Escherichia coli urinary tract infection was treated following removal of the tube cystostomy and subsequent urine culture revealed no evidence of urinary tract infection. The cat retained normal urinary continence and elimination behaviour during the 7-month follow-up period. Vaginourethroplasty could be considered as a salvage option for management of traumatic pelvic urethral rupture in the neutered female cat.  相似文献

The medical records of 39 dogs and 8 cats which had jejunostomy feeding tubes placed using modifications of a previously described surgical technique were retrospectively reviewed. Modifications included the addition of a suture to anchor the feeding tube to the jejunum, the use of a continuous circumferential suture to pexy the jejunum to the abdominal wall, and the placement of a skin suture that penetrated deep into the abdominal wall fascia. All tubes were placed during surgical treatment of a primary intraabdominal disease. Tubes were used for feeding from 1 to 41 days (average 9.7 days). Sixteen patients (34%) developed mild to moderate complications such as chewing at the tube, inadvertent tube removal, tube obstruction, and cellulitis around the ostomy site. Three patients (6%) developed severe complications associated with breakdown of the surgical site. The modified jejunostomy technique was effective for placement of jejunostomy tubes as a complementary procedure to exploratory celiotomy.  相似文献

Interest in noninvasive feeding tube placement in companion animals led to the adaption of a human technique utilizing endoscopy to place nasojejunal feeding tubes. Data from medical records in which nasojejunal feeding tubes were attempted were reviewed. Feeding tubes were attempted and successfully placed in five dogs within a median of 35 min. Feeding tubes remained in place for approximately 7 days. Complications included facial irritation (5/5), sneezing (5/5), fractured facial sutures (4/5), vomiting (3/5), diarrhea (3/5), crimping of feeding tube (3/5), regurgitation (1/5), epistaxis (1/5), clogging of the feeding tube (2/5), and oral migration with premature removal of the feeding tube (1/5). The deployment technique used in this study was found to be cumbersome. Despite minor complications, endoscopy can be used to rapidly and accurately place nasoenteric feeding devices.  相似文献

Dogs and cats that had a percutaneous endoscopic gastrostomy (PEG) tube or surgically placed gastrostomy (SPG) tube inserted were retrospectively analyzed to compare complication rates and the severity of complications. Complication rates and severity scores were not significantly different when the PEG tube group was compared to the SPG tube group in either dogs or cats. Only when data from dogs and cats were combined did PEG tubes have a significantly higher complication rate and significantly greater complication severity scores.  相似文献

OBJECTIVE: To evaluate complications and outcomes associated with use of gastrostomy tubes in dogs with renal failure. DESIGN: Retrospective study. ANIMALS:56 dogs. PROCEDURE: Medical records were reviewed for dogs with renal failure that were treated by use of gastrostomy tubes. RESULTS: Mean +/- SD BUN concentration was 134 +/- 79 mg/dl and mean serum creatinine concentration was 9.0 +/- 3.8 mg/dl. Low-profile gastrostomy tubes were used for initial placement in 10 dogs, and traditional gastrostomy tubes were used in 46 dogs. Mild stoma-site complications included discharge, swelling, erythema, and signs of pain in 26 (46%) of dogs. Twenty-six gastrostomy tubes were replaced in 15 dogs; 11 were replaced because of patient removal, 6 were replaced because of tube wear, and 3 were replaced for other reasons. Six tubes were replaced by low-profile gastrostomy tubes. Gastrostomy tubes were used for 65 +/- 91 days (range, 1 to 438 days). Eight dogs gained weight, 11 did not change weight, and 17 lost weight; information was not available for 20 dogs. Three dogs were euthanatized because they removed their gastrostomy tubes, 2 were euthanatized because of evidence of tube migration, and 1 died of peritonitis. CONCLUSIONS AND CLINICAL RELEVANCE: Gastrostomy tubes appear to be safe and effective for improving nutritional status of dogs with renal failure.  相似文献
