title: Urethral cystoscopic realignment and early end-to-end anastomosis develop different influence on erectile function in patients with ruptured bulbous urethra.
abstract: The objective of this study is to compare the influence on erectile function between urethral cystoscopic realignment and early end-to-end anastomosis treating ruptured bulbous urethra. 58 cases were selected, 32 had urethral cystoscopic realignment (group I) and 26 cases had urethral end-to-end anastomosis (group II). The parameters of P-CDU (Penile Color Duplex Ultrasound), NPT (Nocturnal Penile Tumescence), and IIEF-5 (International Index of Erectile Function) were compared between the two groups 6 months after operation. Group I was higher than group II in IIEF (21 vs 14) with significant differences. With P-CDU we observed an improvement in penile vascularization in group I as confirmed by the detection of an increase in peak systolic velocity (PSV) (26 cm/s vs 16 cm/s, p<0.01) and a decrease in end diastolic velocity (EDV) (3 cm/s vs 6 cm/s p<0.05), resulting in an increase in resistive index (RI) (0.85 vs 0.56, p<0.05). The parameters of NPT showed a significant increase compared to group II (p<0.01) in satisfactory erection number (5 vs 1.5), maximum rigidity (80% vs 42%), and total time that the increase in circumference was greater than 30% of baseline during sleep (100 sec vs 30 sec). Urethral cystoscopic realignment treating ruptured bulbous urethra can reduce the incidence of erectile dysfunction [ED]. A long term follow-up should be studied.
