Surgical Reintervention Rates after Invasive Treatment for Lower Urinary Tract Symptoms due to Benign Prostatic Syndrome: A Comparative Study of More than 43,000 Patients with Long-Term Followup.

No large-scale comparison of the 4 most established surgical approaches for lower urinary tract symptoms due to benign prostate obstruction in terms of long-term efficacy is available. We compared photoselective vaporization, laser enucleation and open simple prostatectomy to transurethral resection with regard to 5-year surgical reintervention rates. A total of 43,041 male patients with lower urinary tract symptoms who underwent transurethral resection (34,526), photoselective vaporization (3,050), laser enucleation (1,814) or open simple prostatectomy (3,651) between 2011 and 2013 were identified in pseudonymized claims and core data of the German local health care funds and followed for 5 years. Surgical reinterventions for lower urinary tract symptoms, urethral stricture or bladder neck contracture were evaluated. Surgical approach was related to reintervention risk using the Kaplan-Meier method and Cox proportional hazards models. A total of 5,050 first reinterventions were performed within 5 years of primary surgery (Kaplan-Meier survival without reintervention: 87.5%, 95% CI 87.2%-87.8%). Photoselective vaporization carried an increased hazard of reintervention (HR 1.31, 95% CI 1.17-1.46, p <0.001) relative to transurethral resection, open simple prostatectomy carried a lower hazard (HR 0.43, 95% CI 0.37-0.50, p <0.001) and laser enucleation of the prostate did not differ significantly (HR 0.84, 95% CI 0.66-1.08, p=0.2). This pattern was more pronounced regarding reintervention for lower urinary tract symptom recurrence (photoselective vaporization: HR 1.52, 95% CI 1.35-1.72, p <0.001; laser enucleation of the prostate: HR 0.84, 95% CI 0.63-1.14, p=0.3; open simply prostatectomy: HR 0.38, 95% CI 0.31-0.46, p <0.001 relative to transurethral resection). Five-year reintervention rates of transurethral resection and laser enucleation did not differ significantly, while photoselective vaporization had a substantially higher rate. Open simple prostatectomy remains superior to transurethral resection with respect to long-term efficacy.
