Abstract:
Objective:To investigate the clinical effect of lingual mucosal augmentation urethroplasty with non-transecting urethral cavernous anastomosis in the treatment of traumatic urethral stricture.Methods:The clinical data of 39 patients with traumatic urethral stricture admitted to our clinical center from March 2023 to December 2023 were retrospectively analyzed. Their mean age was (49.7±2.0)years. The cause of urethral injury was pelvic fracture in 32 cases, riding injury in 5 cases, and iatrogenic injury in 2 cases. Suprapubic vesicostomy tube was indwelled before operation in 39 cases. There was 1 case with hypospadias and 1 case with urethral false passage. 9 patients had urethral dilatation before surgery, 5 had internal urethrotomy operation, 5 had urethroplasty, and 22 had no history of urethral surgery. The International Erectile Function Index (IIEF-5)score of 39 cases last 1 month before surgery was collected and classified.In which, the IIEF-5 score of 19 cases with no or mild erectile dysfunction was median 20 (18, 23)points, the MSHQ-Ejd score was median 16 (11, 19)points, and the number of effective erections was median 4(3, 5)times on the NPT. And in which, the IIEF-5 score of 20 cases with moderate to severe erectile dysfunction was median 10 (3, 14)points, the MSHQ-Ejd score was median 3(1, 7)points, and the number of effective erections was median 1(0, 2)times on the NPT. All 39 cases underwent non-transecting anastomotic lingual mucosal augmentation urethroplasty. The central tendon of the perineum and the ventral side of the bulbar urethra were preserved through perineal approach. The dorsal side of the urethra was mobilized and through the dorsal side of the urethra, the scar of the urethra was enucleated along the mucosa of the urethra. Then the ventral mucosa of the urethra was anastomosed end to end and the dorsal urethra was repaired by lingual mucosa transplantation. The Clavien-Dindo complication grading system was performed. The catheter was removed 4 weeks after operation, and urine flow rate was recorded 1 month after extubation. IIEF-5 score, MSHQ-Ejd score and NPT were recorded 6 months after operation.Results:The mean operation time of 39 cases was (118.0±18.3)min. 39 cases were followed up for median 8.0(6.0, 10.0)months. The Q max ≥15 ml/s in 24 cases. The Q max <15ml/s in 13 cases, of which, the Q max ≥15 ml/s after 1 internal urethrotomy operation in 10 cases and Q max≥15 ml/s after 2 internal urethrotomy operations in 3 cases. 2 cases were still failed to urinate and Q max≥15 ml/s after end-to-end urethral anastomosis. All 39 cases’ Clavien-Dindo complications were graded Ⅰ.Of the 19 cases with no or mild erectile dysfunction, the IIEF-5 score was median 20(17, 23)points, the MSHQ-Ejd score was median 16(11, 19)points, and the number of effective erections was median 4(3, 4)times on the NPT postoperatively, all were not significantly different from those before operation ( P> 0.05). Of the 20 cases with moderate and severe erectile dysfunction, the IIEF-5 score was median 9(4, 13)points, the MSHQ-Ejd score was median 4(2, 7)points, and the number of effective erections was median 1(0, 2)times on the NPT postoperatively, and all were not significantly different from those before operation ( P>0.05). Conclusions:Non-transecting anastomotic lingual mucosal augmentation urethroplasty is a reliable surgical method with few complications for traumatic urethral stricture. Moreover, the operation has little effect on the sexual function of patients.
