RESUMEN

We aimed to compare the short-term outcomes of men who had urodynamic evidence of detrusor underactivity (DU) or detrusor overactivity (DO) of a non-neurogenic etiology as well as bladder outlet obstruction (BOO) and who underwent Holmium Laser Enucleation of the prostate (HoLEP). A database of 322 patients who underwent HoLEP between 2010 and 2014 was analyzed. Patients were classified into three groups according to the results of a preoperative urodynamic study. Preoperative parameters such as International Prostate Symptom Score (IPSS), Quality of Life (QoL) index, IPSS grade, uroflowmetry were compared with postoperative parameters measured at 6 months. There were 138 patients with BOO-only and 89 patients with BOO and detrusor dysfunction including 56 with DO and 33 with DU. The degree of improvement in IPSS-total (BOO: 10.7, DO: 8.3, DU: 7.0; p = 0.023) was greater in the BOO-only group than in the DU group. There were more patients whose IPSS grade improved in the BOO-only group (71%) than in the detrusor dysfunction group (DO: 53.6% and DU: 45.5%). Postoperative IPSS-voiding (4.5 vs 7.0), and Qmax (18 vs 13.7) in the BOO-only group were significantly better than those in the DU group. Additionally, postoperative IPSS-storage (4.7 vs 6.7), and IPSS-total (9.1 vs 12.3) in the BOO-only group were significantly better than in the DO group (all p < 0.05). In conclusion, early surgical management for men with severe LUTS and associated BPH before secondary degeneration occurs may be beneficial for preserving detrusor function and yield better treatment outcomes.

RESUMEN

PURPOSE: To evaluate the perioperative, functional, and oncological outcomes of renal cryoablation (RC) of small renal masses (SRMs) performed in Korea University Hospital. MATERIALS AND METHODS: We reviewed an Institutional Review Board-approved database of 70 patients who underwent RC and were followed up for a minimum of 3 months by a single surgeon in Korea University Hospital from August 2007 to May 2014. Among these patients, 68 patients (79 renal masses) were enrolled in our research. We evaluated perioperative, functional, and oncologic outcomes of RC. RESULTS: A total of 68 patients (79 renal masses) underwent RC in our institution. The mean age of the patients was 62.0 years. The mean tumor size was 2.25 cm. Among the 59 patients who underwent laparoscopic surgery, only 1 patient (1.47%) was converted to open surgery. No other perioperative complications occurred. The mean preoperative and 1-month postoperative estimated glomerular filtration ratio (eGFR) were 71.8 and 68.3 mL/min/1.73 m(2), respectively (p=0.19). The mean 1-year postoperative eGFR was 65.0 mL/min/1.73 m(2) (p=0.25). The mean follow-up period was 59.76 months (range, 3-119 months). Local tumor recurrence occurred in eight tumors (15.4%; a total of 52 renal cell carcinomas). Concerning treatment in the patients with recurrence, five patients underwent re-treatment and three patients are under active surveillance. None of the eight patients who experienced local recurrence had additional recurrence or tumor progression during the follow-up period. In our study, the recurrence-free rate was 83.0% and the cancer-specific survival rate was 100%. Moreover, the 5- and 10-year overall survival rates were both 100%. CONCLUSIONS: Long-term experience with RC in our institution demonstrates that RC is a safe and effective treatment for patients with SRMs.
