We sought to evaluate whether TURP in patients who underwent cystolithotripsy led to a lower recurrence of bladder stones for which a re-cystolithotripsy was necessary.</p> <p><strong>Methods:</strong> Patients (n=127) who underwent transurethral cystolithotripsy with (n=38) or without simultaneous TURP (n=89) between January 2009 and December 2013 were retrospectively included in five centers in the Netherlands. Median followup was 48 months. The primary endpoint was to compare the relative risk between both groups for re-cystolithotripsy due to recurrent bladder stones. Secondary outcomes were the relative risk of urinary retention, the need for a (re-)TURP and the average time until recurrence.</p> <p><strong>Results:</strong> Patients who underwent a cystolithotripsy with a simultaneous TURP had a lower need for re-cystolithotripsy, resulting in a risk reduction of 72%. (relative risk [RR] 0.28 [0.07–1.13], p=0.06, number needed to treat [NNT]=7). The length of in hospital stay (3.4 vs. 1.6 days, p=0.04) and operative time (58 vs. 33 minutes, p<0.01) was longer when a TURP was performed. There was no significant difference in complication rate, occurrence of urinary retention, re- TURP, and re-admission. Eighty-one percent of patients who did not undergo a TURP remained free of bladder stone recurrence. Due to the retrospective nature of the study, essential data concerning prostate volume and micturition analysis was lacking.</p> <p><strong>Conclusions:</strong> A simultaneous TURP in patients who underwent a cystolithotripsy showed a trend towards a protective effect on the need for re-cystolithotripsy.</p>}, number={7}, journal={Canadian Urological Association Journal}, author={Mekke, Sander and Roshani, Hossain and van Zanten, Paul and Grondhuis Palacios, Lorena and Egberts, Joost and Hendriks, Nora and Wijffelman, Mischa and Zonneveld, Willemijn and Merks, Bob and van Loopik, Sarah and Buddingh, Tim}, year={2020}, month={Dec.}, pages={E361–5} }
