To determine the rate of early recurrence of urethral stricture in the first six months in patients who perform hydraulic urethral dilatation(HUD) after optical internal urethrotomy (OIU) and compare the early recurrence rate in patients who perform HUD after OIU with the recurrence rates in patients reported in the literature who undergo OIU without performing HUD.
Prospective descriptive case series.
Urology clinic, Muhimbili Medical Centre, Dar es Salaam, Tanzania.
Patients with symptoms of urethral stricture subsequently radiologically demonstrated to have urethral stricture that was deemed treatable by OIU.
Evaluation included urethrography, renal biochemical profile and urethroscopy at the time of OIU. Patients with strictures no longer than 50 mm, no complete block or marked tortuousness, and no paraurethral sepsis were selected for OIU, urethral catheter for seven days followed by HUD) for one month.
During a follow up period of five to seventeen months (mean 10.1 months), only two out of twenty three patients (8.7%) showed clinical evidence of stricture recurrence. The remaining patients reported normal voiding.
This report suggests that HUD, a cost-free technique, is an effective method for preventing stricture recurrence after OIU. As follow up of these and subsequent patients continue, it is hoped that this not-so-well-known technique will undergo evaluation at other centres in our region.
确定在光学尿道内切开术(OIU)后进行水囊尿道扩张术(HUD)的患者在头六个月内尿道狭窄的早期复发率,并将OIU后进行HUD的患者的早期复发率与文献中报道的未进行HUD而接受OIU的患者的复发率进行比较。
前瞻性描述性病例系列。
坦桑尼亚达累斯萨拉姆穆希姆比利医疗中心泌尿外科诊所。
有尿道狭窄症状且随后经放射学证实患有尿道狭窄且被认为可通过OIU治疗的患者。
评估包括在OIU时进行尿道造影、肾脏生化指标检查和尿道镜检查。选择狭窄长度不超过50毫米、无完全阻塞或明显迂曲且无尿道旁感染的患者进行OIU,留置尿道导管7天,随后进行HUD 1个月。
在5至17个月(平均10.1个月)的随访期内,23名患者中只有2名(8.7%)出现狭窄复发的临床证据。其余患者排尿正常。
本报告表明,HUD这种无需费用的技术是预防OIU后狭窄复发的有效方法。随着对这些患者及后续患者随访的继续,希望这项不太知名的技术能在我们地区的其他中心接受评估。
