Objectives: To compare the efficacy and reliability of Ho:YAG laser lithotripsy (FILL) and pneumatic lithotripsy (PL) in the treatment of bladder stones in patients with benign prostatic hyperplasia and stones >= 20 mm who were transurethrally treated in the same surgical session. Methods: We studied the data of patients with benign prostatic hyperplasia and >= 20 mm bladder stones who were treated with transurethral resection of the prostate and cystolithotripsy in the same session, obtained between January 2010 and February 2014 from three urology clinics. All patients underwent bipolar plasmakinetic (PK) transurethral resection of the prostate. For treatment of the bladder stone, either HLL or PL was applied. A total of 62 patients were divided into two groups: PK-PL (Group 1, n = 29) and PK-HLL (Group 2, n = 33). The data of both groups were analyzed for stone dimensions, stone fragmentation time, total operating time, hospitalization duration, prostate dimensions, success rates, and complications. Results: Group 1 included 29 patients with a mean age of 70 +/- 7.6 (range, 57-85) years, whereas Group 2 included 33 patients with a mean age of 67.5 +/- 10.5 (range, 45-84) years. In Group 1, five patients had mucosa injury, one patient had residual stone, and one patient had bladder perforation. In Group 2, three patients had mucosa injury, three patients had postoperative fever, and one patient had residual stone. Total operation time and stone fragmentation time were significantly lower in Group 2(p < 0.05). The remaining analyzed data were similar (p > 0.05). Conclusion: PK-HLL using a single shaft without the need for repeated access has the advantages of shorter fragmentation and operatidn time. Copyright (C) 2015, Asian Surgical Association.

Predictive Factors Affecting the Success of Nephrectomy for the Treatment of Nephrogenic Hypertension: Multicenter Study
(2021) Vuruskan, Ediz; Ercil, Hakan; Unal, Umut; Alma, Ergun; Anil, Hakan; Sumbul, Hilmi Erdem; Deniz, Mehmet Eflatun; Goren, Mehmet Resit; 33873196
Introduction: The aim of our study is to evaluate the predictive factors affecting the success of treatment with nephrectomy in patients with poorly functioning kidney and nephrogenic hypertension. Methods: Data for patients who underwent nephrectomy with a diagnosis of nephrogenic hypertension in 3 centers between May 2010 and January 2020 were analyzed. In the postoperative period, if the blood pressure (BP) was below 140/90 mm Hg without medical treatment, it was accepted as complete response; if the arterial BP was below 140/90 mm Hg with medical treatment or less medication, it was accepted as partial response; and if BP did not decrease to normal values, it was accepted as unresponsive. Demographic characteristics, duration of hypertension, preoperative and postoperative BP values, and presence of metabolic syndrome were statistically evaluated. Results: Our study consisted of 91 patients with a mean preoperative hypertension duration of 23.3 +/- 12.1 months. Among patients, 42 (46.2%) had complete response, 18 (19.8%) had partial response, and 31 (34.0%) had no response. Preoperative systolic and diastolic BP values were not effective on treatment success (p = 0.071, p = 0.973, respectively), but the increase in age and hypertension duration (p = 0.030 and p < 0.001, respectively) and the presence of metabolic syndrome (p = 0.002) significantly decreased the complete response rates. Conclusions: Preoperative hypertension duration, advanced age, and presence of metabolic syndrome are predictive factors affecting the response to treatment in patients who undergo nephrectomy due to nephrogenic hypertension.
Treatment of Moderate Sized Renal Pelvis Calculi: Stone Clearance Time Comparison of Extracorporeal Shock Wave Lithotripsy and Retrograde Intrarenal Surgery
(2016) Ercil, Hakan; Alma, Ergun; Bas, Okan; Sener, Nevzat Can; Vuruskan, Ediz; Kuyucu, Faruk; Unal, Umut; Goren, Mehmet Resit; Evliyaoglu, Yalcin; https://orcid.org/0000-0002-2001-1386; 26945652; Y-6143-2019
Purpose: To compare the stone clearance times in patients undergoing extracorporeal shock wave lithotripsy (SWL) or retrograde intrarenal surgery (RIRS) for single radiopaque renal pelvis stones 10-20 mm in size. The results of this study may guide urologists and patients and aid in selecting the optimal preoperative treatment. Materials and Methods: Between January 2013 and February 2015, we conducted a retrospective study and collected data from 333 patients treated with SWL (n = 172) or RIRS (n = 161). We included successfully treated patients with a single radiopaque renal pelvis stone 10-20 mm in size to calculate stone clearance times. Results: The average stone size for the SWL group was 14.62 +/- 2.58 mm and 14.91 +/- 2.92 mm for the RIRS group. The mean Hounsfield unit (HU) of the patients was 585.40 +/- 158.39 HU in the SWL group and 567.74 +/- 186.85 HU in the RIRS group. Following full fragmentation, the mean stone clearance time was 26.55 +/- 9.71 days in the SWL group and 11.59 +/- 7.01 days in the RIRS group (P <.001). Conclusion: One of the most overlooked parameters in urinary stone treatments is stone clearance. We believe this study will shed light for those who aim to conduct larger randomized prospective studies.
