Objective: To determine the efficacy and safety of a novel minimally invasive design for treating bulky vesical calculi and large benign prostatic hyperplasia (BPH) simultaneously. Methods: 76 patients with large bladder stones (>4 cm) and large BPH (≥50 cm3) were treated from August 2008 to January 2011. 38 patients (group 1) underwent transurethral cystolithotripsy followed by transurethral resection of the prostate (TURP), 38 patients (group 2) received percutaneous cystolithotripsy within a laparoscopic entrapment bag and TURP by two surgeons simultaneously. 72 patients were followed up for 1 year. Patient demographics, perioperative parameters and follow-up data were compared. Results: Patient baseline characteristics were comparable in the two groups. In group 1, 3 patients converted to open surgery and received blood transfusion, 4 patients had postoperative fever, 2 had residual stones and 1 developed urethral stricture postoperatively. In group 2, the mean total operative and the operative times for stone management were 71.6 and 30.1 min, respectively, the mean hemoglobin decrease was 0.80 g/dl, no patients received blood transfusion and no complications occurred, significantly superior to group 1. Conclusions: Percutaneous cystolithotripsy using a laparoscopic entrapment bag associated with TURP by two surgeons simultaneously is a highly effective, safe and minimally invasive method for managing large vesical calculi and large BPH.
