Aim: To assess the outcomes of men treated for urolithiasis at the time of radical prostatectomy.
Methods: From 1991 to 2010, 22 patients were retrospectively identified who were treated simultaneously (n = 10) at radical prostatectomy, or (n = 12) within 120 d prior to prostatectomy, for urolithiasis. Clinical characteristics were reviewed including: type of prostatectomy and stone surgery, location and amount of stone burden, perioperative change in hemoglobin and creatinine, stent frequency, total hospital d, stone-free rates, additional stone procedures and complications. Long-term functional outcomes including stress urinary incontinence and bladder neck contracture were reported. Differences between cohorts (simultaneous vs staged treatment) were assessed.
Results: Among men undergoing radical prostatectomy, primary stone procedures included 12 ureteroscopy, 6 shock wave lithotripsy, 2 open nephrolithotomy and 2 percutaneous nephrolithotomy. In staged shock wave lithotripsy there were 4 complications and 3 additional procedures vs 1 (P = 0.5) and 0 (P = 0.2) in the simultaneous cohort. Meanwhile in staged ureteroscopy there were 5 complications and 1 additional procedure vs 1 (P = 0.2) and 1 (P = 0.9) in the simultaneous cohort. Additional procedures for residual stones was greater among patients with asymptomatic upper tract calculi 3 (60%) relative to patients with symptomatic stones 2 (13%; P = 0.02). Likewise, patients with proximal or multiple calculi had a greater total hospital days 5.5 vs 4.1 (P = 0.04), additional procedures 6 vs 0 (P = 0.04) and lower stone-free rates 39% vs 89% (P = 0.02) relative to men with distal stones. Finally, there was no difference in the incidence of bladder neck contracture (P = 0.4) or stress urinary incontinence (P = 0.7) between cohorts.
Conclusion: Ureteroscopic treatment of symptomatic distal urolithiasis at radical prostatectomy appears to be safe and efficacious with a low rate of adverse postoperative outcomes.
