Objectives Penile urethral stricture disease not associated with hypospadias is rare, and there is a wide range of commonly used surgical repair techniques for this disease. We sought to compile a multi‐institutional database of patients who had surgical correction of strictures in the penile urethra not limited to the meatus, and who had no history of hypospadias, for analysis using the Trauma and Urologic Reconstructive Network of Surgeons length, urethral segment and etiology classification system. Methods A retrospective database from 13 institutions was compiled of patients who had undergone surgical correction of Trauma and Urologic Reconstructive Network of Surgeons length, urethral segment and etiology urethral stricture segments S2b/S2c and excluding E5, with a minimum follow‐up time of 4 months. Failure was defined as cystoscopically confirmed recurrence of a stricture measuring less than 16‐Fr. Results We analyzed 222 patients with a median age of 57 years and a follow‐up of 49 months. The overall surgical success rate was 80.2%. On multivariate analysis, the two variables identified that were predictive of surgical success were stricture length ≤2 cm as well as use of a buccal mucosa graft as compared to use of a fasciocutaneous flap, which had success rates of 83% and 52%, respectively ( P = 0.0004). No statistically significant differences were found based on incisional approach or surgical technique, nor were outcomes different based on etiology or preoperative patient demographics. Conclusions Surgical repair of penile urethral strictures of non‐hypospadiac origin have a favorable overall success rate, at 80.2%. Regardless of incisional approach or surgical technique, all operations appear to have similar outcomes other than repairs using fasciocutaneous flap, which were statistically less successful than those using buccal mucosa graft.

Purpose: Lower urinary tract symptoms among adult men can significantly impact quality of life. We evaluated complications based on prostate size following plasmakinetic enucleation of the prostate. Materials and Methods: Patients were grouped into the small prostate group (SPG, <75 g) and large prostate group (LPG, >75 g) based on preoperative imaging. Patient data on demographics, comorbidities, preoperative international prostate symptom score (IPSS), bother index (BI), prostate-specific antigen (PSA) if indicated, postvoid residual volume (PVR), indwelling catheter or self-catheterization status, and any prior surgical intervention were evaluated. Postoperative IPSS, BI, and PVR values were assessed at 6 weeks, 4 months, and yearly. Postoperative urge urinary incontinence (UUI), stress urinary incontinence (SUI), and pad use were assessed. Results: Between September 2015 and December 2020, 296 patients who underwent bipolar enucleation with minimum follow-up of 4 months were evaluated. Postoperative IPSS, BI, PVR, and PSA values at all time points were significantly decreased compared with preoperative values ( p < 0.05). There was no significant difference in the complications between groups. Univariable and multivariable analysis found that size <75 g was predictive of stricture formation and bladder neck contracture (BNC). UUI was more common at 6 weeks in the SPG, and SUI was more common at 6 weeks in the LPG, but no difference was noted at the 4-month and 1-year time points. Pad use was equal between the two groups at all time points. Conclusions: Plasmakinetic enucleation of the prostate provides an effective treatment option for prostates of all sizes; however, prostates <75 g have a higher rate of BNC and urethral strictures compared with those >75 g.
