We aimed to evaluate the long-term therapeutic effect of transurethral split of the prostate (TUSP) with a newly improved double-columnar balloon catheter on patients with benign prostatic hyperplasia (BPH).

Total 565 BPH patients (mean age 73.6 years, range 46–94 years) who underwent TUSP surgery between January 2006 and January 2015 were included. Patient's baseline characteristics, prostate size, PSA, preoperative and postoperative maximum urinary flow rate (Qmax), postvoid residual (PVR), international prostate symptoms score (IPSS) and quality of life (QOL) score, perioperative data and postoperative complications were recorded.

The mean preoperative prostates size was 48.6 ± 8.2 mL (range 33–230 mL), and the PSA level was 0.8 to 18.6 ng/mL. The mean duration of TUSP procedure from the catheter localization to the split of capsula prostatica was ∼10 minutes. After surgery, the mean Qmax increased from 5.2 ± 1.4 to 12.8 ± 2.2 mL/s (P < 0.001). Patients had improved mean PVR, QOL score, and IPSS after TUSP (76 ± 8 vs 20 ± 8.5 mL, 4.6 ± 0.2 vs 1.4 ± 0.3, and 20.2 ± 4.4 vs 6.6 ± 1.1, respectively, all P < 0.001). Until September 2014, 328 patients were successfully followed up for a long-term period of 38 to 99 months. There was no other case of recurrence with dysuria despite 2 recurrent cases.

The TUSP with a double-columnar balloons catheter was a safe and long-term efficient treatment for BPH, with minimal invasion, short operative time, few postoperative complications, and low recurrence rate.
