    Abstract:
    PURPOSE: To evaluate long-term efficacy and safety of low-pressure transurethral resection of the prostate for prostates < 70 cc (group 1) vs. > 70 cc (group 2). PATIENTS AND METHODS: In this study patients operated with monopolar TURP between 2009 and 2012 were evaluated retrospectively. During surgery a specially designed trocar (18 Fr) was placed suprapubically and connected to a suction pump to maintain stable low-pressure conditions. After sample size calculations, long-term follow-up was completed for 70 invited patients in each group up to 9/2015. RESULTS: Follow-up period was 57 vs. 56 months for group 1 and 2, respectively (p = 0.56). At baseline there was no significant difference in age, IPSS, peak flow, and post void residual (PVR). Mean prostate volume was 47 cc (15-65) vs. 100 cc (70-163). Mean operating time was 55.4 vs. 82.6 min (p = 0.00). Blood transfusion was necessary in 0.0 vs. 2.9% (p = 0.16), and 0.0 vs. 1.4% developed TUR syndrome (p = 0.32). At follow-up mean relative improvement in IPSS was 63 vs. 57% (p = 0.29), QoL 64 vs. 64% (p = 0.93), peak flow 139 vs. 130% (p = 0.85), and PVR 58 vs. 63% (p = 0.80). Long-term complications included recurring adenoma in 1.4 vs. 4.3% (p = 0.31), and stricture in 7.2 vs. 5.8% (p = 0.73). 1 patient in each group reported worsening incontinence symptoms. CONCLUSIONS: In terms of safety and efficacy, the aforementioned modality of standardized monopolar TURP using suprapubic suction was non-inferior for prostates > 70 cc compared to the same procedure for prostates < 70 cc. This technique is a potential low-cost alternative for clinics that cannot afford modern laser approaches. STUDY REGISTER NUMBER: DRKS00006527.
