自1985年1月至1994年3月,我们治疗因前列腺增生（BPH）所致肾功能不全58例,行膀胱造瘘33例,其中17例在造瘘后3～5月行二期开放前列腺摘除:保留导尿25例,其中18例经2～3周保留导尿后行开放前列腺摘除:对另6例经41～56天保留导尿肾功能仍未恢复正常血肌酐（Cr）180μmol/L左右,同样顺利完成手术,无手术死亡病例。我们体会:对血Cr32μmd/L左右无严重心肺疾患者尽可能保留导尿,待肾功能正常后行开放前列腺摘除。如经1～2月膀胱引流肾功能未恢复正常（血Cr180μmol/L左右）,经适当术前术中与术后处理仍能安全手术。保留导尿后手术比膀胱造瘘后手术可有缩短治疗时间,避免二次手术和防止手术切口延期愈合的优点。
From January 1985 to March 1994, we treated 58 cases of renal insufficiency due to benign prostatic hyperplasia (BPH) and 33 cases of cystostomy, of which 17 cases underwent second-stage open prostate in March-May after fistula Endemic removal: 25 cases of catheterization were retained, of which 18 cases were left urethral catheterization after 2 to 3 weeks and prostatectomy was performed. For the other 6 cases, the retention of urinary catheter renal function after 41 to 56 days was not restored to normal serum creatinine (Cr) 180μmol / L or so, the same successful completion of surgery, no surgical deaths. We understand: on the blood Cr32μmd / L or so no serious heart and lung disease as much as possible to retain catheterization until the normal renal function after the opening of the prostate removed. If the bladder drainage from January to February renal function did not return to normal (blood Cr180μmol / L or so), after appropriate preoperative and postoperative management can still be safe surgery. Retaining the catheter after surgery than after the operation of bladder fistula can shorten the treatment time, to avoid secondary surgery and prevent surgical incision delayed healing advantages.
