“…In the study of Vasudeva et al [21] who compared the dorsal onlay versus ventral onlay for treating bulbar urethral stricture by BMG, they reported 92.5% success rate when using dorsal onlay technique and 90% success rate when using ventral onlay procedure. In a metanalysis that was done by Bagchi et al [22] , who compared between the different types of grafts that used in urethral reconstructions after stricture, they found that the success rate when using BMG is 85.9%, which is in line with our study findings.…”

“…The type of the operative procedure was significantly affected the success rate (P value < 0.003) as it was high in dorsal onlay (97.1%) more than ventral onlay (66.6%), which disagrees with the result of Bagchi et al [22] , who found no significant difference between the two procedures as regarding the success rate. Volume of blood loss significantly affects the success rate (P value = 0.001) as the percentage of succeed patients in those who lost < 500 ml blood was 87.3%% and in those who lost > 500 ml was 0%.…”

Background: A prevalent urologic illness in men, urethral stricture is accompanied by a significant financial burden as well as a decline in the quality of life for afflicted men and their families. Buccal mucosal grafts (BMG) are now often utilised to repair lengthy anterior urethral strictures. Objective: To assess the effectiveness of buccal mucosal graft urethroplasty for long-segment anterior urethral stricture resulting from various etiologies, including previously complex hypospadias repair. Patients and methods: This prospective cohort study included 65 patients with long-segment anterior urethral stricture due to different etiologies. Complete medical history and physical examination were done to each patient during enrollment. Urological investigations were done to confirm the diagnosis and to determine the accurate site of urethral stricture. All patients underwent buccal mucosal graft urethroplasty and all outcomes were reported. Results: The mean age of the patients was 27.6±13.15 SD years. Regarding the presenting symptoms, 63.1% of the panties complained from obstructive symptoms, and 39.9% complained from retention symptoms. Post hypospadias repair failure was the main etiology of strictures (n = 24; 36.9%). The success rate was found to be 84.6%, while 15.4% had recurrent stricture. The volume of blood loss was significantly affected success rate (P value=0.001). Also, the success rate was significantly affected by age (P value < 0.04), stricture site (P value < 0.006), cause of stricture (P value < 0.01), type of BMG urethroplasty (P value < 0.003), wound infection (P value < 0.001), hematoma formation (P value < 0.01), and catheterization time (P value < 0.001). Conclusion: BMG either dorsal or ventral onlay is an effective technique for treatment of urethral strictures of different etiologies.

Background: Normally female urethral stricture (FUS) is uncommon and underdiagnosed condition. It is raising a diagnostic challenge for the physicians. It is the one of the rarely known urological entity. Urethral dilatation is the traditionally used treatment for urethral stricture (FUS). The female urethroplasty have shown the promising outcomes. Objective: The objective of the study was to compare the outcome of the dorsal onlay urethoplasty FU obtained by using buccal mucosal graft and vaginal wall graft. The FU is more effective treatment for female urethral stricture (FUS) as compared to the repeated dilatation. Study design: It is a retrospective study with the statistical approach, conducted at Urology Department, Pakistan Institute of Medical Sciences Islamabad from June 2021 to November 2021. Material and Methods: The women who underwent the dorsal onlay urethropasty at the urology department of the hospital were included in the study. The outcomes of BMG and VWG were compared. The re-intervention was marked as failure. The association symptom score, postvoid residual urine (PVR), cystourethrogram, cystoscopy and uretheral calibration were included in the assessment. Operating time, catheter time, etiology, location, length, prior interventions and suprapubic cystostomy were the other parameters that was also reported. For the statistical analysis the Mann-Whitney test, t-test and proportion test was performed. Results: The calculated mean age of the patients included in the group was 48 years. Its range was between the 26 to 76 years. The women visited the urology department of the hospital from June 2021 to June 2022. The average follow-up was for 26 months. The AUA symptoms changes from 22 to 6, Qmax from 4ml/s to 26ml/s and RVR from 185ml to 7ml. The operating time was the only parameter showed the difference, while other remained the same. The 94% was the overall urethral patency rate. Conclusion: For the substitution of dorsal onlay urethroplasty the use of VWG and BMG is highly recommended. It is an efficient and reliable treatment method. There are very low chances of complication and it has an easy protocol. Apparently, no specific change was observed in the FUS treatment by BMG and VWG. Keywords: Female urethral stricture (FUS), buccal mucosal graft, vaginal wall graft, postvoid residual urine (PVR), dorsal onlay urethroplasty.

ObjectivesTo evaluate the feasibility of correcting penile urethral strictures at the bulbus glandis using buccal mucosal graft (BMG) urethroplasty in dogs.Study designProspective clinical trial.AnimalsFive male dogs with urethral strictures located at the bulbus glandis.MethodsUrethrotomy was performed throughout the entire length of the urethral stricture including ~0.5 cm healthy urethra proximal and distal. The scarred tissue and unhealthy mucosa of the strictured urethra were completely excised. The graft was harvested from the buccal mucosa and tubularized at the stricture site using a urethral catheter as the skeleton. The catheter was maintained for 14 days after surgery and removed when no urethral leakage was identified on a positive‐contrast retrograde urethrogram. The dogs were discharged after spontaneous urination was confirmed. Six months postoperative follow‐up was completed for all dogs with repeated positive contrast urethrogram and an owner questionnaire to score urinary function and quality of life.ResultsThe five dogs recovered well following surgery and only one dog experienced a minor complication. All dogs were able to urinate normally after catheter removal. No evidence of leakage was identified on a 14 day postoperative retrograde positive contrast urethrogram and clinically at a median follow‐up time of 182 days (range, 182–186). All owners scored the urinary function as excellent and ranked their satisfaction very high 6 months after the procedure.ConclusionBuccal mucosal graft urethroplasty has positive outcomes for dogs with penile urethral strictures.
