    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.

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

    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.

    Current Minimal Invasive Surgery Treatment For Kidney Stones: Bezmialem Experience
    (2016-08-01T00:00:00Z) AKÇAY, MUZAFFER; Tepeler, Abdulkadir; TOSUN, MUHAMMED; Basibuyuk, Ismail; Elbir, Fatih; KARDAŞ, SİNA; Akman, Tolga; Armagan, Abdullah; Tasci, Ali Ihsan; AKÇAY, MUZAFFER; TOSUN, MUHAMMED; KARDAŞ, SİNA
    Objective: We aimed to present the outcomes of patients with symptomatic kidney stones treated with percutaneous nephrolithotomy (PNL) or retrograde intrarenal surgery (RIRS). Methods: The medical records of patients with symptomatic renal calculi treated with PNL or RIRS between November 2010 and May 2015 were obtained. Demographic characteristics such as age; sex; BMI; stone size and location; and perioperative data including operation, fluoroscopy, and hospitalization time; and success and complication rates were assessed. Results: Standard (n:336), mini-PNL (n:51), ultramini-PNL (n:37) and microperc (n:47) were performed for 471 renal units. RIRS was the treatment method for 290 renal unites. In the PNL group, the mean patient age was 44.5 (1-83) years and BMI was 26.9 kg/m2. The mean stone size was 27.6 mm. In the RIRS group, the mean age and BMI were 47.1 (1-86) years and 25.1 kg/m2, respectively. The mean operation, fluoroscopy, and hospitalization times were 70.0 (20-240) min, 45.1 (17-610) s, and 2.4 (1-20) days, respectively, in the PNL group. On the other hand, the mean operation, fluoroscopy, and hospitalization times were 62.5 (40-180) min, 29.8 (0-96) s, and 26.4 (12-120) h, respectively, in the RIRS group. Whine stone free status was achieved in 88% in the PNL group; this rate was lower (80%) in the RIRS group. Conclusion: Both PNL and RIRS are efficient minimally invasive methods with low morbidity and high success rates for the treatment of symptomatic kidney stone disease.
