Buccal mucosal graft urethroplasty in male cats with traumatic complete urethral rupture

OBJECTIVE To evaluate the feasibility of buccal mucosal graft urethroplasty for repairing complete urethral rupture in cats. ANIMALS 15 male domestic shorthair cats with traumatic complete urethral rupture. PROCEDURES In each cat, a section of buccal mucosa was harvested, sutured, and formed into a tubule by use of an 8F indwelling catheter as support. This tubular graft was connected to both ruptured ends of the urethra to renew the urinary passage. The catheter was left in place until the absence of leakage was confirmed by positive contrast retrograde urethrography. After spontaneous urination was confirmed, cats were discharged from the hospital. Six months later, urethrography was repeated and owners were asked to score their cats’ urinary function and quality of life. RESULTS 13 cats recovered well following surgery, with no complications in the oral cavity or surgical site and no signs of difficulty or discomfort when urinating. Urethrography 2 weeks and 6 months after surgery revealed no stricture or leakage in the abdominal cavity. The 2 remaining cats developed a urethral stricture and underwent second surgery with a successful outcome. At the 6-month follow-up, 14 cats had only mild urinary signs, and 1 cat had incontinency. Owners indicated they were delighted (n = 14) or pleased (1) with their cats’ quality of life. CLINICAL RELEVANCE Buccal mucosa was found to be a good source of graft tissue for performance of urethroplasty in male cats, yielding satisfactory outcomes with few postoperative complications. The described technique may be suitable for severe and complicated cases of urethral rupture in male cats.

Delayed Diagnosis and Treatment of Traumatic Testicular Dislocation: A Case Report and Literature Review

Traumatic testicular dislocation is a rare complication secondary to different kinds of accidents. A 61-year-old man, who was injured by wall collapse and was diagnosed as pelvic fracture and posterior urethral rupture 5 months ago, came to the urologic department to seek urethral reconstruction. However, thorough physical examination and imaging examination confirmed a round mass in the right inguinal region and an empty right scrotum, which support diagnosis of testicular dislocation. The patient did not take the initiative to complain about that because he thought the right testis had been destroyed by the accident already. So the patient underwent fiber cystourethroscopy, urethral reconstruction, and orchiopexy. No testicular atrophy was confirmed at follow-up. We reviewed previous reports about traumatic testicular dislocation and analyzed the cause of delayed diagnosis.

Fracture of the penis in Jos, Nigeria: review of cases in 2020

Background: Penile fracture is a urological emergency and requires urgent medical attention. There was a relative upsurge in 2020. Diagnosis is usually based on typical history and examination findings suggestive of penile fracture. The objective of this study was to determine the demographics, clinical presentation and management of fracture of the penis.Methods: All patients who presented at the accident and emergency in 2020 with penile fracture were studied. The patients age, time to presentation, mechanism of injury, clinical features (cracking sound, pain, immediate detumescence, penile swelling, urethral bleeding and acute urinary retention) were recorded. Intraoperative findings (location of corpora rupture, length of tear and urethral rupture) were recorded and analysed.Results: Twelve patients were studied. The mean age was 34.8 years, range (20 years to 56 years). 58.3% presented within 24 hours of trauma. The commonest mechanism of penile fracture was sexual intercourse with the woman on top position (58%). 75% of the patients heard a popping sound. All patients had pain, detumescence and penile swelling (N=12) 100%. Two patients had urethral bleeding (N=2) 16.7%, with one having associated urethral rupture (N=1) 8.3%. Two patients had acute urinary retention (16.7%). Rupture of the right corpora occurred in 50%, 8.3% had bilateral rupture of the corpora. All the patients had repair of the corporal rupture. Urethral injury was repaired primarily. Erection and voiding post-repair were satisfactory.Conclusions: Fracture of the penis is a urological emergency. Diagnosis can be made based on typical history and examination findings. Prompt surgical intervention is advised to avoid complications and erectile dysfunction.

Bladder neck reconstruction in girls’ pelvic fracture bladder neck avulsion and urethral rupture

Background Girls’ pelvic fracture bladder neck avulsion and urethral rupture is rare however it causes great morbidity. The management is complex and not standard yet. We report our experience and a technique of bladder neck reconstruction with anterior bladder wall flap. Methods We retrospectively analysed data of 5 girls with pelvic fracture bladder neck avulsion and urethral rupture admitted to our institution from July 2017 to October 2019. They all came to our institution with a suprapubic tube. Patients’ trauma was all initially treated at other hospitals, 4 had suprapubic cystotomy and 1 had urethral realignment. One girl also had three other urethroplasties at other hospitals. We took pubectomy, posterior ureth roplasty and bladder neck reconstruction with anterior bladder wall flap in these 5 girls. Post-operative assessments included voiding cystourethrography, uroflowmetry and urethroscopy after urethral catheter removal. Verbal consent to participate was obtained from the parent or legal guardian of the children. Results Operation time ranged from 120 to 180 min. Follow-up time is 12 to 27 months. Uroflowmetry showed that maximum urine flow rate improved significantly. Cystourethrography indicated good continuity of the urethra. Two girls had urinary incontinence postoperatively but were continent 3 months later. One patient developed vesical-abdominal fistula and got repaired by surgery 6 months later. She was continent ever since. Other complications were not observed during the follow-up period. Conclusions Our method of bladder neck reconstruction using bladder flap as a patch is feasible and provides good continence, especially for those with serious bladder neck avulsion and urethral rupture caused by extensive trauma and those who had posttraumatic urethral distraction needed second repair.

Comparison of surgical indications and short- and long-term complications in 56 cats undergoing perineal, transpelvic or prepubic urethrostomy

Objectives The aim of this study was to compare indications, complications and mortality rates for perineal urethrostomy (PU), transpelvic urethrostomy (TPU) and prepubic urethrostomy (PPU). Methods A retrospective review of, and follow-up owner questionnaire for, cats undergoing urethrostomy between 2008 and 2018, at a single referral hospital, were performed. Results Fifty-six cats underwent urethrostomy (PU, n = 37; TPU, n = 8; PPU, n = 11). The presenting problem was significantly associated with urethrostomy technique ( P <0.001). For PU cats, feline idiopathic cystitis (FIC; n = 21 [56.7%]) was the most common problem, whereas for PPU cats, trauma (n = 9 [81.8%]) was most common ( P <0.001). Urethrostomy technique was associated with imaging diagnosis ( P <0.001) of the urethral lesion. Most PU cats had no diagnostic imaging lesion (n = 15 [40.5%]) or obstructive calculi or clots (n = 10 [27.0%]), and all PPU cats had urethral rupture. Ten (90.9%) PPU cats had a pelvic lesion, while 21 (56.7%) PU cats had a penile lesion. TPU cats had a range of presenting problems and imaging diagnoses. Short- and long-term complications were reported in 33/55 (60.0%) and 11/30 (36.7%) cats, respectively. The number of cats with long-term complications was greater among PPU cats ( P = 0.02). Short-term dermatitis ( P = 0.019) and long-term incontinence ( P = 0.01) were associated with PPU. Short-term mortality was 5.6% and long-term mortality was 13.3%; both were independent of urethrostomy technique. Quality of life post-urethrostomy, across all techniques, was graded as good by 93% of owners. Conclusions and relevance In this study, PU was the most common feline urethrostomy technique indicated for FIC. Short-term urethrostomy complications are common, irrespective of urethrostomy technique. Long-term complications are less frequent but more common with PPU.

Novel Treatment Strategy for Management of Traumatic Bulbar Urethral Rupture Using Temporary Urethral Stent after Primary Realignment; Retrospective Comparison between Thermo-Expandable Urethral Stent and Self-Expandable Polymer-Coated Urethral Stent

A variety of retrievable and other types of temporarily placed stents are currently being used. However, only a few studies have considered primary endoscopic realignment with temporary urethral stent insertion in the event of traumatic bulbar urethral injury. We aimed to compare the clinical effectiveness and complications between thermo-expandable urethral stents and polymer-coated bulbar urethral stents (BUSs) for the treatment of traumatic bulbar urethral strictures. Between September 2011 and March 2018, 30 patients who had been diagnosed with complete bulbar urethral rupture following blunt trauma underwent temporary urethral stent placement after primary realignment. Thermo-expandable nickel-titanium alloy urethral stents were placed for 15 patients (group M), and retrievable self-expandable polymer-coated BUSs were placed for another 15 patients (group A). All stents were removed within 6 months after placement. The complications and maintained patency rates were compared between the two groups. The mean stent indwelling period was 5.0 ± 2.5 months in group M and 4.9 ± 4.0 months in group A. Both groups maintained high patency rates (Group M 12/15 (80.0%) and group A 13/15 (86.7%)). Five patients who developed urethral stricture underwent direct visual internal urethrotomy (DVIU), and no patients required repeat DVIU or open surgical urethroplasty. Both groups maintained the mean maximal urinary flow rate (Qmax) at 12 months after stent removal. Discomfort (46.7% vs. 6.7%), granulation tissue formation (73.3% vs. 26.7%) and post-void dribbling (80.0% vs. 20.0%) were more frequent in group M than in group A (p = 0.013, p = 0.011 and p = 0.001, respectively). In conclusion, both stents were effective for managing traumatic complete bulbar urethral rupture after primary realignment. However, the thermo-expandable urethral stents had a higher complication rate while the stent was in situ than the BUSs.
