Öğe A comparison of antegrade percutaneous and laparoscopic approaches in the treatment of proximal ureteral stones(Hindawi Publishing Corporation, 2014) Topaloğlu, Hikmet; Karakoyunlu, Ahmet Nihat; Sarı, Sercan; Özok, Hakkı Uğur; Sağnak, Levent; Ersoy, HamitPurpose. To compare the effectiveness and safety of retroperitoneal laparoscopic ureterolithotomy (RLU) and percutaneous antegrade ureteroscopy (PAU) in which we use semirigid ureteroscopy in the treatment of proximal ureteral stones. Methods. Fifty-eight patients with large, impacted stones who had a history of failed shock wave lithotripsy (SWL) and, retrograde ureterorenoscopy (URS) were included in the study between April 2007 and April 2014. Thirty-seven PAU and twenty-one RLU procedures were applied. Stone-free rates, operation times, duration of hospital stay, and follow-up duration were analyzed. Results. Overall stone-free rate was 100% for both groups. There was no significant difference between both groups with respect to postoperative duration of hospital stay and urinary leakage of more than 2 days. PAU group had a greater amount of blood loss (mean hemoglobin drops for PAU group and RLU group were 1.6 ± 1.1 g/dL versus 0.5 ± 0.3 g/dL, resp.; P=0.022). RLU group had longer operation time (for PAU group and RLU group 80.1 ± 44.6 min versus 102.1 ± 45.5 min, resp.; P=0.039). Conclusions. Both PAU and RLU appear to be comparable in the treatment of proximal ureteral stones when the history is notable for a failed retrograde approach or SWL. The decision should be based on surgical expertise and availability of surgical equipment. © 2014 Hikmet Topaloglu et al.Öğe A comparison of retrograde intrarenal surgery and percutaneous nephrolithotomy for management of renal stones>= 2 CM(Urology and Nephrology Research Centre, 2017) Sarı, Sercan; Özok, Hakkı Uğur; Çakıcı, Mehmet Çağlar; Özdemir, Harun; Baş, Okan; Karakoyunlu, Ahmet Nihat; Sağnak, Levent; Şentürk, Aykut Buğra; Ersoy, HamitPurpose: In this retrospective study, we aimed to compare the outcomes in patients who have been treated with percutaneous nephrolithotomy (PNL) and retrograde intrarenal surgery (RIRS) on renal stones ? 2 cm size. Materials and Methods: We evaluated patients who underwent PNL or RIRS for renal stones ? 2 cm size between November 2011 and November 2014. Stone size, operation, fluoroscopy and hospitalization time, success rates, stone-free rates and complication rates were compared in both groups. Patients were followed for three months. Results: 254 patients were in the PNL Group. 185 patients were in the RIRS Group. The mean age was 46.88 and 48.04 years in PNL and RIRS groups, respectively. The patient and stone characteristics (age, gender, Body Mass Index, kidney anomaly, SWL history and stone radioopacity) were similar between two groups. The mean stone size preoperatively was significantly larger in patients who were treated with PNL (26.33mm.vs 24.04 mm.; P = .006). In the RIRS group, the mean stone number was significantly higher than PNL group (P < .001). The mean operative, fluoroscopy and hospitalization time were significantly higher in PNL group (P < .001). The stone-free rate was 93.3% for the PNL group and 73.5% for the RIRS group after first procedure (P < .001). No major complication (Clavien III-V) occurred in the RIRS group. Conclusion: Although the primary treatment method for renal stones ? 2cm size is PNL, serious complications can be seen. Therefore, RIRS can be an alternative treatment option in the management of renal stones ? 2 cm size.Öğe Endovascular treatment of a blunt trauma which caused massive perineoscrotal haematoma in a child(Kare Publishing, 2015) Karakoyunlu, Ahmet Nihat; Yıldırım, Mahir; Topaloğlu, Hikmet; Özok, Hakkı Uğur; Sağnak, Levent; Ersoy, HamitUrethral injuries are primarily suggested in patients who are presented at the emergency service with straddle trauma. In addition, perineal vascular injuries are rarely observed in such traumas. In the literature, perineal, vascular injuries have been reported with high-flow priapism in many cases. We will present a treatment for a pure pudendal artery that disturbs hemodynamics. This technique is based on endovascular technique with minimal invasion in pediatric male patients who have followed a fall accompanied neither with urethral injury nor with priapism and those who could not have been controlled with conservative treatment but have a massive hemorrhage, which cannot be controlled with conservative treatment. © 2015 by Erciyes University School of Medicine.Öğe Malfunctioned and fractured penile prosthesis caused by cross placement: case report(Elsevier Inc., 2015) Karakoyunlu, Ahmet Nihat; Sarı, Sercan; Özdemir, Harun; Topaloğlu, Hikmet; Özok, Hakkı Uğur; Sağnak, Levent; Ersoy, HamitPenile prosthesis is a functional option for patients who have erectile dysfunction after failed medical and intracavernosal treatments. Malleable penile prosthesis is a good alternative. Penile prosthesis implantation is a surgical process. Seldomly complications occur. In this study we presented a 61 y old man who has malfunctioned and broken penile prosthesis due to cross implantation.Öğe Migration of an forgotten intrauterine device into the urinary bladder(Gulhane Medical School, University of Health Sciences, 2013) Sağnak, Levent; Ersoy, Hamit; Aksun, Fuat; Özok, Hakkı Uğur; Karakoyunlu, Ahmet Nihat; Topaloğlu, HikmetSpontaneus migration of the intrauterine devices(IUD) into the bladder is a rare complication. We report and describe the clinical outcome and management of one such case of intravesical IUD. The diagnosis was confirmed after cystoscopic visualization. Endoscopic examination allowed removal of the IUD.
