摘要:目的:探讨口腔颊黏膜尿道背侧镶嵌补片法治疗长段前尿道狭窄围术期的护理措施。 〖方法:术前做好口腔、会阴部及肠道准备,重视患者心理护理;术后重视尿管护理,维持吻合口低压状态,做好口腔及饮食护理,适当限制活动,注重并发症的观察与及时处理。结果:术后2～3月手术成功率达到92.4%,仅7.5%患者复发。结论:保证围手术期护理措施的质量对尿道成形手术的效果起到了重要的作用。 Abstract: Objective: To explore the perioperative nursing measures for the patients who underwent urethroplasty with dorsal onlay autogenetic oral ducal mucosa. Methods: Preoperative preparation includes oral cavity, perinea region,bowel cleansing and psychological nursing. Postoperatively, urinary catheter nursing is crucial to keep the anastomosis tension acceptablely low. Other postoperative care includes oral cleansing, activity restricting, discovering and dealing promptly with the complications. Results: Success rate was 92.4% 23 months after operation .Only 7.5% patients relapsed. Conclusions: Intensive perioperative nursing care was obviously helpful in improving the outcome of urethroplasty.
Objective To investigate the therapeutic effect of pedicled scrotal septal flap urethroplasty on longsegment posterior urethral stricture and to assess its appl ication value. Methods From January 2003 to December 2007, 24 patients (age range, 6-54 years old) with long-segment urethral stricture underwent pedicled scrotal septal flap urethroplasty.The duration of the disease was 1-5 years. The stricture was caused by traumatic urethral injury or disruption in 22 cases,postoperative compl ication of suprapubic transvesical prostatectomy in 1 case, and recurrent urethral infection due to long-term indwell ing urinary catheter in 1 case. Urethroscopy or cystourethrography examination confirmed that all cases had urethral stricture 2.0-5.5 cm in length. Eleven cases were compl icated with urethral false passage, 6 with urethral fistula, 2 with intestinal fistula, and 6 with erectile dysfunction. The result of excretion urography of bilateral upper urinary tracts was negative in all cases. Pedicled scrotal septal flap 2.5 cm × 2.0 cm-6.5 cm × 2.5 cm in size was harvested during operation, and urethroplasty was performed. Results Volume of blood loss during operation was 100-500 mL (average 270 mL). The operative time was 90-220 minutes (average 135 minutes). All flaps survived. All wounds healed by first intention. All patients had normal urination after operation. Over the follow-up period of 12-36 months (average 18.6 months), 1 of the 24 patients suffered from urinary incontinence, 2 from urethral stricture, 1 from urethral stricture and urethral fistula, and 1 from urethral diverticulum around the distal anastomosis. Those patients got normal urination after symptomatic treatment. No urethral stone, urinary incontinence, and new case of erectile dysfunction occurred. The maximum urinary flow rate 16 months after operation was 14-21 mL/s (average 17.6 mL/s). Voiding cystourethrography 22 months after operation showed unblocked urinary tract and no formation of stricture and fistula. Conclusion Pedicled scrotal septal flap urethroplasty, featured by simple operative method, easy flap harvest, and high survival rate of flap, is one of safe and effective methods for treating long-segment posterior urethral stricture.
ObjectiveTo discuss the reoperation methods of urethral stricture after urethroplasty of hypospadias and their effectiveness.MethodsBetween September 2010 and April 2018, 169 patients with urethral stricture after urethroplasty of hypospadias, who underwent ineffective conservative treatments first, were accepted. The age ranged from 1 year and 7 months to 41years with a median age of 5 years and 8 months. The stricture located at the external urethral orifice in 80 cases, internal anastomosis connection in 87 cases, and constructed urethra in 2 cases. The symptoms of urethral stricture occurred at 2 weeks to 52 months after urethroplasty, with a median time of 4.5 months. The patients with external urethral orifice stenosis were treated with urethral meatus augmentation (74 cases) and urethral advancement (6 cases). The patients with internal anastomosis connection stenosis were treated with internal urethrotomy with urethroscopy (10 cases), urethrotomy and one-stage urethroplasty (26 cases), and urethrostomy (51 cases) including 43 cases of two-stage urethroplasty. The patients with constructed urethral stricture were treated with urethrolysis.ResultsOne hundred and fifty-four patients were followed up 6–86 months with an average of 47 months. The stenosis was relieved in 137 cases, and re-stenosis in 12 cases, urethral fistula in 4 cases, all of which were treated successfully. In addition, 1 case with mild urethral diverticulum did not need to be treated.ConclusionIf it is ineffective for the conservative treatment of urethral stricture after urethroplasty of hypospadias, appropriate surgical treatments could be selected according to the location and length of the stricture, local tissue conditions, complications, and so on.
