The outcome of nontransecting anastomotic urethroplasty in recurrent bulbar urethral stricture and its impact on sexual functions: A prospective observational study

Purpose: The management of recurrent bulbar urethral stricture had no consensus and faced many challenges such as the risk of failure, ischemia, and sexual dysfunction. Therefore, this study aimed to assess the outcome of nontransecting anastomotic urethroplasty in recurrent bulbar urethral stricture disease (USD) less than 3 cm and its impact on sexual functions. Material and methods: This is a prospective descriptive study that included patients with recurrent bulbar USD ≤ 3 cm. Full history taking and clinical examination, including International Prostate Symptoms Score (IPSS) and International Index of Erectile Function (IIEF-5), were documented. Moreover, retrograde urethrogram, uroflowmetry, and penile Doppler were undergone. The nontransecting urethroplasty techniques were performed: Heineke-Mikulicz principle stricturoplasty for stricture ≤1 cm without excision of the stricture and nontransecting excision and primary anastomosis without transecting the corpus spongiosum for stricture 1 to 3 cm. Each patient was routinely evaluated through a 12-month follow-up using IPSS and IIEF, uroflowmetry, and postvoiding residual urine. Results: Thirty-three patients were included in the study with a mean stricture length of 1.45 ± 0.7 cm. Twelve patients had failed previous urethroplasty, while 21 patients had previous visual internal urethrotomy. Nontransecting excision and primary anastomosis in 14 patients and Heineke-Mikulicz principle stricturoplasty in 19 patients were performed. There was no recurrence of stricture urethra, except for one patient, who required visual internal urethrotomy at a 3-month follow-up, with mean postoperative IPSS of 3.04 ± 2.745, Qmax 23.89 ± 2.714 mL/s, and postvoiding residual urine 26 ± 33 cc. No significant differences were reported between pre- and postoperative IIEF (18.61 ± 5.448 versus 19.33 ± 5.599, respectively, P = 0.236). Conclusion: Nontransecting urethroplasty can achieve a high success rate in short recurrent bulbar USD without the potential sexual morbidity.
