Abstract:
OBJECTIVE:To summarize the clinical outcomes of partial pubectomy assisted anastomotic urethroplasty for male patients with pelvic fracture urethral distraction defect (PFUDD) and discuss the skills of partial pubectomy.
METHODS:The clinical data of 63 male patients with PFUDD were retrospective reviewed. The procedure of the anastomotic urethroplasty was as follows: (1) circumferentially mobilizing the bulbar urethra; (2) separating the corporal bodies; (3) performing the urethral anastomosis after partial pubectomy and exposure of the healthy two ends of the urethra.
RESULTS:The mean age of the patients was (39.2±15.6) years (range: 15-72 years). The median time between incidents and operation was 15 months (range: 3-240 months) and the mean length of stricture was (3.85±0.91) cm (range: 1.5-5.5 cm). All the patients had undergone suprapubic cystostomy in acute setting. Thirteen patients (20.6%) were re-do cases and the patients who had undergone dilation, direct vision internal urethrotomy (DVIU), and open primary realignment were 22 (34.9%), 8 (12.7%), and 8 (12.7%), respectively. Assisted with partial pubectomy, the anastomotic urethroplasty had been successfully performed in all the patients. The mean time of operation was (160.2±28.1) min (110-210 min), and the mean evaluated blood loss was (261.1±130.3) mL (100-800 mL). There were 3 cases (4.8%) with perioperative blood transfusions. The postoperative complications were bleeding and urinary tract infection, which were controlled conservatively. The mean maximum urine flow rate was (23.7±7.4) mL/s (15.0-48.2 mL/s) after removing the catheters 4 weeks after urethroplasty. The median follow-up was 23 months (12-37 months). The urethroscopy showed 2 cases of stricture recurrences and 1 case of iatrogenic penile urethral stricture due the symptoms of urinary tract infection and decreased urine flow and all of them were successfully managed with dilation.
CONCLUSION:Partial pubectomy can effectively reduce the gap between the ends of the urethra and promote tension-free anastomosis during the anastomotic urethroplsty for patients with PFUDD. The skills of the procedure include good exposure of the anterior surface of pubic symphysis between the separated corporal bodies, carefully mobilizing and securing the deep dorsal vein of the penis, removing the partial pubic bone and the harden scar beneath the pubic bone for good exposure of the proximal urethral end.
