Background
Long anterior urethral stricture due to variable etiological factors constitutes a challenge for reconstruction.
We evaluated our centers experience with cases of long anterior urethral stricture due to different etiologies that were managed by 2-stage substitution urethroplasty using buccal mucosal graft procedure.
Methods
During the period between November 2009 and November 2016. All cases with long anterior urethral stricture that were planned for substitution urethroplasty in our department were enrolled in this study. The first stage was excision of most fibrotic areas of the urethral plate, the remaining of the urethra is laid open and augmented with buccal mucosal graft for second stage closure after 6–9 months.
Results
The study included 123 patients who underwent first stage, 105 patients of them underwent second stage urethroplasty. Eighteen cases were missed after first stage. The mean (range) age was 38.4 (17–60 years). The mean (range) stricture length was 8.3 (4–13 cm). The cause of stricture was idiopathic in 47, inflammatory in 15, lichen sclerosus in 26 and post failed hypospadias repair in 35 patients. First stage was complicated by graft contracture in 11 (8.9%) patients that needed re-grafting, 5(4.1%) patient had bleeding from the buccal mucosa site that needed haemostatic sutures, oral numbness was reported in 7 (5.7%) patients. Second stage was complicated by wound dehiscence in 2(1.9%) patients, restricture in 11 (10.5%), fistula in 6 (5.7%) patients, meatal stenosis in 3 (2.9%). The overall success rate was 79.1% (83 cases out of 105) with a mean (range) follow-up of 34.7 (10–58 months).
Conclusions
Staged urethroplasty using buccal mucosal graft procedure is an effective surgical option for patients with long anterior urethral strictures especially for patients with lichen sclerosus and those with failed previous surgical repair.

Background:
Transurethral resection of bladder tumors (TURBT) is the standard management for urinary bladder tumors; however, new techniques as Thulium laser en bloc resection of bladder tumors (TmLRBT) have been introduced as a substitute to TURBT.
Objectives:
In this study safety, efficacy, and tumor recurrence after TmLRBT and TURBT were prospectively compared in patients with primary (<4 cm) bladder tumors.
Patients and Methods:
Between August 2019 and May 2021, patients with primary (<4 cm) bladder tumors were enrolled. Patients were randomized between the two procedures. All perioperative data were collected prospectively. Pathological specimen findings and recurrence rates were reported during follow-up visits.
Results:
Sixty patients underwent TURBT, and another 60 had TmLRBT. No significant differences were detected in patient demographics or preoperative tumor characteristics between the two groups. Operation time was less (28.2 vs. 38.9 min, P < 0.001), and rate of bladder perforation was lower with TmLRBT compared to TURBT (3.3% vs. 15.0%, P = 0.027). In the TmLRBT group, higher rate of muscle detection (95.0% vs. 78.3%, P < 0.001) in the pathological specimen, and lower rate of tissue destruction (0.0% vs. 21.6%, P < 0.001) were obtained compared to TURBT. Recurrence rate in cases of nonmuscle invasive bladder cancer was lower with TmLRBT (6.7% vs. 33.0%, P < 0.001).
Conclusion:
In this study, TmLRBT showed reduced operative time with lower perforation rates. Higher detection of detrusor muscle and less tissue destruction in the pathological specimen were obtained with TmLRBT, as well as lower rates of tumor recurrence. These findings suggest that TmLRBT is a safe and efficacious substitute to TURBT in tumors <4 cm.
The likelihood of adverse pathological outcomes at radical prostatectomy is lower in men diagnosed with favorable risk prostate cancer on repeat/subsequent prostate biopsy than in men diagnosed on initial prostate biopsy, and may represent an important consideration in risk stratifying cases of favorable risk prostate cancer.
