ABSTRACT

Objective To investigate the causes and prevetion of urethral stricture after transurethral resection of the prostate(TURP). Methods A retrospective analysis was carried out in 945 cases,who were treated by TURP in our hospital during February 2002-February 2008.Among the cases,21 patients(aged 62 to 84 years with a mean of 72.4 years) developed urethral stricture in 3 weeks to 24 months after the operation.In the cases,anterior urethral stricture was detected in 13 patients(61.9%),posterior urethral stricture was found in 5(23.8%),and bladder neck contracture was diagnosed in 3(14.3%).Results The pateints were cured by simple urethral dilation(13,61.9%),urethroplasty(2,9.5%),urethroplasty plus urethral dilation(2,9.5%),transurethral resection(1,4.8%),or electroresection of the bladder neck(3,14.3%).The patients were followed up for 6 to 36 months(mean,13 months),during which,all the 21 cases recovered without recurrence.The rate of urethral stricture after TURP was 3.7%(18/483) during February 2002 to August 2005,which was significantly higher than that between September 2005 and February 2008(0.6%,3/462;?2=10.292,P=0.001).Conclusions Unskilled operation and short indwelling time of urethral catheter after the surgery are the major reasons for urethral stricture after TURP.Regular follow-up and early treatment are the keys to cure of the disease.
