We aimed to measure the intrarenal pelvic pressure (IPP) during microperc and compare it with the levels of conventional PNL. A total of 20 patients with 1- to 3-cm renal calculi resistant to shock wave lithotripsy were treated either with microperc (Group-1, n: 10) or conventional PNL (Group-2, n: 10) by the same surgical team. The IPP was measured during different stages (entrance into the collecting system, stone fragmentation, and before termination) of the procedures by an urodynamic machine using the 6Fr ureteral catheter. All the variables were statistically compared between the two groups. The demographic values of the patients were similar. The operation time and duration of hospitalization were significantly prolonged in conventional PNL group (p = 0.034, p = 0.01, respectively). The mean drop in hematocrit levels was significantly lower in microperc group (3.5 +/- A 1.5 vs. 1.8 +/- A 0.8; p = 0.004). The IPP was significantly higher in microperc group during all steps of the procedure. The highest level of the IPP was measured as 30.3 +/- A 3.9 and 20.1 +/- A 3.1 mmHg in Group 1 and Group 2, respectively (p < 0.0001). However, the complication and success rates were found comparable. In conclusion, we demonstrate that the level of IPP is significantly increased during microperc compared to conventional PNL. Microperc should be used cautiously in cases with impaired drainage of the collecting system.Publication Metadata only The optimal settings of holmium YAG laser in treatment of pediatric urolithiasis.(2021-01-21T00:00:00Z) Ersoz, Cevper; Ilktac, ABDULLAH; Kalkan, Senad; Danacioglu, Yavuz Onur; Silay, Mesrur Selcuk; ERSÖZ, CEVPER; İLKTAÇ, ABDULLAH; DOĞAN, BAYRAM; KALKAN, SENADThe aim of this study is to present our experience on the use of the holmium:yttrium-aluminum-garnet (Ho:YAG) laser in pediatric patients for pediatric urolithiasis and describe the optimal settings. A total of 116 children who underwent urolithiasis treatment (percutaneous nephrolithotomy (PNL), ureterorenoscopy (URS), retrograde intrarenal surgery (RIRS)) were included. The mean age of the patients was 8.4 ± 5.2 years (1-18). The mean follow-up was 26 ± 8.8 months (9-45). There was no difference between the mean stone sizes of PNL and RIRS patients (p = 0.816). Operations were performed with 200, 272, and 365-μm fibers. In mini-URS, stone fragmentation was achieved with the energy settings set between 0.5 and 1 J and frequency set to > 8 Hz. In RIRS, fragmentation was achieved with the setting of 0.5-0.8 J at 10-20 Hz. Stone fragmentation was performed with energy settings of 0.8 to 2 J between 5 and 15 Hz for PNL. There was no significant difference between the stone-free rates of the PNL and RIRS (p = 0.150). Four postoperative complications occurred (Clavien II), which included febrile urinary infections in two patients who underwent mini-URS, one patient who underwent PNL, and one patient who underwent RIRS. Our results confirmed that Ho-YAG laser can be effectively used in children for stone treatment by using low-energy high-frequency settings for URS and RIRS and a high energy setting for PNL.Publication Metadata only Tam Üretral Rüptüre Eşlik Eden Penil Kırıkların Cerrahi Tedavisi(2022-02-01T00:00:00Z) Ersöz, Cevper; İlktaç, Abdullah; Çolakoğlu, Yunus; Şimşek, Abdulmuttalip; Kalkan, Senad; ERSÖZ, CEVPER; İLKTAÇ, ABDULLAH; KALKAN, SENADPublication Metadata only A Modified Antegrade Stenting Technique for Laparoscopic Pyeloplasty in Infants and Children(2016-01-01) Kalkan, SENAD; Ersoz, CEVPER; ARMAGAN, Abdullah; TASCI, Ali Ihsan; SILAY, Mesrur Selcuk; KALKAN, SENAD; ERSÖZ, CEVPERObjective: There are 2 critical steps of stent placement during laparoscopic pyeloplasty (LP) in children. Introduction to the ureteropelvic junction and passing through the ureterovesical junction. We aimed at overcoming those 2 steps by creating a modified technique. Methods: Consecutive 27 children undergoing transperitoneal laparoscopic dismembered pyeloplasty by a single surgeon were prospectively enrolled into this study. The modifications of our technique are using an Amplatz dilator and a closed tip stent. Results: The mean age of the children was 6.7 (range 4 months-17 years). The mean time of stent insertion was 2.7 +/- 2.0 (2-6) min and the operative time was 128.3 +/- 17.6 (90-180) min. The mean number of days of hospital stay was 2.0 +/- 0.4 (1-3). After a mean follow-up period of 20.3 +/- 4.2 (14-30) months, no operative failure was detected. Conclusion: Our modified technique is a completion of the current armamentarium for stent placement during LP in infants and children. (C) 2016 S.
