    (Springer, 2021) Guler, Ahmet Gokhan; Karakaya, Ali Erdal; Dogan, Ahmet Burak; Kandur, Yasar
    Background We retrospectively analyzed the initial results of laparoscopic pyeloplasty, among pediatric patients undergoing the procedure by transperitoneal access. Methods We retrospectively reviewed the medical records of patients who were operated with transperitoneal laparoscopy-assisted pyeloplasty at our institution between 2015 and 2020. Results The mean age of the 51 patients (M/F = 36/15) was 59 +/- 49.8 months. The mean preoperative renal pelvis anterior-posterior diameter was 32.9 +/- 13.4 mm, and the relative renal function was 42 +/- 12.1% on the operation side. Forty-three (84.3%) patients had no excretion on MAG3 examination preop. The number of patients with no excretion decreased to 10 (19.7%) after surgery. One of them underwent a successful endopyelotomy; eight of them underwent a successful laparoscopic re-pyeloplasty. There was nothing to do in only one patient whose DRF decreased to 11%. The mean anterior posterior diameter decreased significantly to 16.7 +/- 11.2 mm after surgery (p < 0.001). Conclusion Preoperative increased renal pelvis anterior-posterior diameter detected in our study was found to be a risk factor in the failure of transperitoneal laparoscopy-assisted pyeloplasty procedure.

    OUR RESULTS FOR RIGID URETEROSCOPY AND LASER LITHOTRIPSY IN PEDIATRIC AGE GROUP
    (2021) Güler, Ahmet Gökhan; Karakaya, Ali Erdal; Doğan, Ahmet Burak; Kandur, Yaşar
    Objective: Urolithiasis is an important disease that can lead topermanent kidney dysfunction and severe clinical symptoms inpediatric patients. We aimed to present our findings of rigidureteroscopy combined with Holmium YAG laser lithotripsy.Material and Methods: We retrospectively reviewed theultrasonography, and medical records of pediatric patients withurolithiasis who were operated in Sutcu Imam UniversityDepartment of Pediatric Surgery, Kahramanmaraş betweenApril 2018 and December 2019.Results: Sixty-one pediatric patients (M/F=38/23) withurolithiasis were enrolled in this study. The mean age was6.7±4.9 years (range 3 month-17 years). Thirteen (34.2%) malepatients need an urgent operation (rigid ureteroscopy combinedwith Holmium YAG laser lithotripsy) while the correspondingnumber was 4 (17.4%) in female patients. The differencebetween two sexes was statistically non-significant (p=0.156).Thirty-two male patients (84.2%) and 12 (52.2%) femalespatients had a successful operation (rigid ureteroscopy combinedwith Holmium YAG laser lithotripsy). The difference betweenthe two sexes was statistically significant (p=0.019). The ratio offemale patients with right-sided stone was significantly greaterthan the corresponding rates of male patients (p=<0.001). Therewas no difference between infants (<3 years of age) and toddlers(>3 years of age) with respect to gender, side of stone, proceduralsuccess, and need for urgent surgery (p>0.05). Regressionanalysis showed that female gender was a risk factor for a failedattempt (OR=-0.313, 95% CI: 0.052 – 0.528; p=0.0018).Conclusion: Safe and effective stone treatment can beperformed considering that more than one operation can beperformed in infants and children with mini ureteroscopy andholmium laser. However, while evaluating this treatment optionin female patients, alternative treatment methods such as flexibleor percutaneous nephrolithotomy may be preferred.
