Abstract: Objective To 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. Methods This 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. Results A 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). Conclusions In 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.
