Objective: To compare the results of transperitoneal laparoscopic nephrectomy in patients with atrophic and hydronephrotic kidneys. Material and methods: Clinical data were collected from 35 patients who had undergone laparoscopic nephrectomies for atrophic or hydronephrotic non-functioning kidneys between January 2010 and March 2014. Comparative analysis was carried out between the two groups examining demographic characteristics, imaging modalities, etiology, operative times, port numbers, conversion to open surgery, complications, pre- and post-operative hemoglobin and creatinine values, transfussion rates and length of hospital stays. Results: Laparoscopic nephrectomy was performed for atrophic kidneys in 20 (57%) patients and for hydronephrotic kidneys in 15 (42%) patients. In the atrophic group, 3 patients (15%) required transfusion because of bleeding but none of the patients required conversion to open surgery. In the hydronephrotic group one patient (6.6%) required transfusion and conversion to open surgery because of bleeding. Both of the groups were similar in terms of postoperative hospital stay but compared to the atrophic kidneys, hydronephrotic ones were associated with a longer total operative times (90.1 min vs. 73.6 min, p=0.03). Any serious complication (except for bleeding) and mortality were not encountered in both groups. Conclusion: Laparoscopic nephrectomy is a safe and effective minimally invasive technique that can be used in atrophic and hydronephrotic non-functioning kidneys.

Endoscopic Guided Additional Access for Staghorn Calculi

2014-10-01T00:00:00Z, Ziypak, Tevfik, ADANUR, Şenol, Tepeler, Abdulkadir, Erdem, Mehmet Remzi, AKÇAY, MUZAFFER, Armagan, Abdullah, ÖZBEY, İsa, POLAT, Özkan, AKÇAY, MUZAFFER

Background and Purpose: Flexible nephroscopy is an important technique in the management of staghorn renal calculi to reach peripheral calices. In this study, we present our experience with flexible nephroscopy and fluoroscopy-guided additional access creation for staghorn renal calculi.

Laparoscopic-Assisted -Microperc- of a Stone in a Pelvic Kidney of a 3-Year-Old Girl

2013-02-01T00:00:00Z, Tepeler, Abdulkadir, Silay, Mesrur Selcuk, Armagan, Abdullah, Basibuyuk, Ismail, Akman, Tolga, AKÇAY, MUZAFFER, Onol, Sinasi Yavuz, AKÇAY, MUZAFFER

Treatment of kidney stones in pelvic ectopic kidneys of children is a challenging procedure for urologists. Herein we report a case of laparoscopy-assisted -microperc- in a 3-year-old girl with a stone in her pelvic ectopic kidney. This micro-optical system is helpful in confirming the percutaneous access and provides the possibility of fragmenting the stone without the necessity of dilating the tract.

The All-Seeing Needle Instead of the Veress Needle in Pediatric Urologic Laparoscopy

2013-11-01T00:00:00Z, Silay, Mesrur Selcuk, Tepeler, Abdulkadir, Sancaktutar, Ahmet Ali, Kilincaslan, Huseyin, ALTAY, BÜLENT, Erdem, Mehmet Remzi, Hatipoglu, Namik Kemal, AKÇAY, MUZAFFER, Akman, Tolga, Armagan, Abdullah, AKÇAY, MUZAFFER

Purpose: To investigate the feasibility of the all-seeing needle for safe entry and creation of pneumoperitoneum in pediatric urologic laparoscopy. Patients and Methods: A total of 14 children underwent various transperitoneal urologic laparoscopic procedures. The all-seeing needle, which is 4.85F in diameter, was used for safe entry into the abdominal cavity at the site of the umblicus in all cases. The microoptic was integrated with the light system and connected via a zoom ocular enabling direct visualization of the layers between the skin and the peritoneal cavity. Once the intraperitoneal access was obtained, CO2 pneumoperitoneum was created from one port of the three-way connector attached to the proximal part of the needle. Then the laparoscopic trocars were placed under vision of the microoptical system. Results: Mean age of the children was 4.52.9 years. In all children, the all-seeing needle was safely introduced into the abdominal cavity under direct vision. Then, CO2 pneumoperitoneum was succesfully performed. The mean time for optical puncture was calculated as 1.1 +/- 0.8 minutes. No complication was encountered during the introduction of the needle, creation of the pneumoperitoneum, and placement of the trocars. Conclusions: The all-seeing needle appears to be beneficial in safe entry and for creating pneumoperitoneum in laparoscopic pediatric urology cases. It eliminates the disadvantages of the Veress needle, which is blunt insertion, and may possibly prevent complications.
