- PublicationMetadata onlyThe comparison of laparoscopic pyelolithotomy and percutaneous nephrolithotomy in the treatment of solitary large renal pelvic stones(2012-10-01T00:00:00Z) Tefekli, Ahmet; Tepeler, Abdulkadir; Akman, Tolga; AKÇAY, MUZAFFER; Baykal, Murat; Karadag, Mert Ali; Muslumanoglu, Ahmet Y.; de la Rosette, Jean; AKÇAY, MUZAFFERThe aim of the study is to investigate whether laparoscopic pyelolithotomy (LPL) could find a place in the management of large renal pelvic stones which are generally considered as excellent indications for percutaneous nephrolithotomy (PNL). Between 2006 and 2009, 26 consecutive patients with large (> 4 cm(2)) renal pelvic stones were treated by LPL and their charts were compared to 26 match-paired patients treated with PNL during the same period. The patients were matched for age, BMI, stone size and location as well as presence of congenital anomalies. Perioperative and postoperative findings were compared. The mean age, mean stone size, rate of congenital anomalies, history open renal surgery and shock wave lithotripsy were similar in both groups (p > 0.05). The mean operation time was 138.40 +/- A 51.19 (range 70-240) min in LPL group as compared to 57.92 +/- A 21.12 (range 40-110) min in PNL group (p < 0.0001). There was one (3.8%) open conversion in the LPL group due to dense perirenal adhesions making the dissection difficult. The ureteropelvic junction (UPJ) obstruction concomitant to pelvic stones was successfully repaired laparoscopically in two cases. The mean drop in postoperative hemoglobin level was 0.9 +/- A 0.6 (range 0-2) g/dl in LPL group and 1.7 +/- A 1.1 (range 0-4) g/dl in PNL group (p = 0.024). Hospitalization was significantly shorter in PNL than LPL group (p = 0.0001). Stone-free rates were similar. Laparoscopic pyelolithotomy is associated with a longer operation time, is more invasive, and requires more skills when compared to PNL. However, LPL is associated with less blood loss. Laparoscopic pyelolithotomy is indicated for congenitally anomalous kidneys and especially in patients with concomitant UPJ.
- PublicationOpen AccessThe 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, MUZAFFERPurpose: 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.

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.
