OBJECTIVETo investigate the perioperative benefit of suprapubic cystostomy in bipolar transurethral resection of the prostate (B-TURP) for treatment of benign prostatic hyperplasia (BPH) below 80 g.

METHODSThis retrospective study was conducted in patients undergoing B-TURP for BPH below 80 g, who were stratified with respect of suprapubic cystostomy in B-TURP. The end points including the safety, efficiency, complications and nursing care were compared between the two groups.

RESULTSA total of 585 patients were enrolled, including 366 in cystostomy group and 219 in non-cystostomy group. The two groups showed similar postoperative reduction of serum sodium (0.06 vs 0.54 mmol/L, P>0.05), hematocrict (2.44% vs 2.89%, P>0.05), and blood hemoglobin concentration (9.62 vs 10.42 g/L, P>0.05), with comparable weight of resected prostate (42.50 vs 43.76 g, P>0.05). The operation time was significantly longer in cystostomy group than in non-cystostomy group (90.75 vs 76.28 min, P<0.05), but the rate of blood transfusion and incidences of postoperative fever and catheter blocking were comparable between the two groups. Compared with the non-cystostomy group, cystostomy group had significantly longer time for bladder washing (3.15 vs 2.57 days, P<0.05), catheter indwelling time (5.19 vs 4.15 days, P<0.05), and hospital stay after the operation (7.36 vs 5.65 days, P<0.05).

CONCLUSIONSIn B-TURP for BPH below the weight of 80 g, suprapubic cystostomy is associated with a longer time for operation, bladder washing, catheter indwelling and postoperative hospital stay, and thus provides no obvious benefits for the patients.
