Abstract Introduction: There has been a significant change in surgical treatment of benign prostatic hypertrophy (BPH) over the last two decades. Most importantly, laser surgery (coagulation, vaporization, or enucleation) has been growing in popularity as an alternative to standard transurethral prostatectomy (TURP) or other procedures. Our goal was to analyze the trends of BPH surgeries and compare outcomes of laser surgery to TURP, the two most common alternative surgeries. Materials and Methods: We used the New York Statewide Planning and Research Cooperation System (SPARCS) data to identify patients diagnosed as having BPH who underwent BPH-related surgery from October 2000 to December 2011. Age, insurance, individual comorbidities, and average hospital volumes were assessed. Bivariate and multivariate regression models were used to analyze predictors of laser use. In-hospital outcomes were then compared between laser and TURP in a balanced propensity-matched cohort. Results: Ninety thousand six hundred seventy patients underwent BPH surgery. Laser surgery usage increased from 6.4% to 44.5% over 10 years (p<0.0001). TURP declined significantly from 72.2% to 48.3% (p<0.0001). Patients with Medicaid were less likely to undergo laser therapy than those with private insurance (odds ratio [OR]: 0.58, 95% confidence interval [CI]: 0.48, 0.69). Mid- and high-volume institutions were more likely to use laser treatment than low-volume centers (OR: 2.26, 95% CI: 1.22, 4.2; OR: 4.07, 95% CI: 1.75, 9.46, respectively). In the matched cohort, both laser and TURP patients had similar complication rates with more frequent electrolyte disorders in TURP patients (2.9% vs 2.3%, p=0.001). Conclusions: TURP remains the most common procedure. However, the rate of use has declined over time. In contrast, laser use has significantly increased. Laser treatment was utilized more in younger patients, in those privately insured, in hospitals with high volumes of BPH procedures, and in patients with fewer comorbid conditions. Both surgeries are safe with no differences in terms of occurrences of morbidity and complications.

Abstract

Objective: To assess national trends of iatrogenic complications and associated burden of care among patients undergoing open and minimally invasive prostatectomy using a population-based cohort. Methods: Using the nationally representative cohort, we identified patients who were diagnosed with prostate cancer, and underwent prostatectomy during 2001 and 2011. We determined the risk of iatrogenic complication and length of stay (LOS) over time among open and minimally invasive surgery (MIS) patients. Hierarchical multivariable logistic regression was performed to assess the changes over time and elucidate independent predictors of iatrogenic complications. Results: We identified 556,932 and 219,434 prostate cancer patients undergoing open and minimally invasive prostatectomy. We found that iatrogenic complications for MIS were less frequent in later years (years 09-11 vs. year 01-02 odds ratio (OR), 0.21; 95% confidence intervals (CI), 0.09-0.40). MIS was associated with higher risk of iatrogenic complications in early period (years 01-02 OR, 3.81; 95% CI, 1.72-8.41), but lower risk in late period (years 09-11 OR 0.72 95% CI 0.61-0.86). Patients who experienced iatrogenic complications tended to have longer LOS (Median: Open vs. MIS, 4 days vs. 3 day) than those who didn’t (Median: Open vs. MIS, 2 days vs. 1 day), regardless of procedure type. Conclusion: We found that minimally invasive prostatectomy is associated with lower risk of iatrogenic complications when compared with open surgery (OS). However, as “learning curve” is overcome over time, MIS becomes safer than OS. Iatrogenic complications are not benign and seem to be associated with higher burden of inpatient care.
