Results of laparoscopic management of stones in horseshoe kidney at a tertiary referral hospital

Abstract

The management of kidney stones in patients with horseshoe kidney is a challenge for all urologists, given the low prevalence of the anomaly. There are very few reports of treatment through laparoscopic pyelolithotomy in the literature. Our aim was to share the results and experience obtained in the treatment of stones in horseshoe kidney through transperitoneal laparoscopic pyelolithotomy. Methodology: A retrospective, observational, cross-sectional, analytic study was conducted on patients diagnosed with horseshoe kidney and kidney stones, confirmed by non-contrast abdominal tomography, and treated through transperitoneal laparoscopic pyelolithotomy, within the time frame of January 2010 and January 2020. Results: There were 4 cases of renal pelvic stones in horseshoe kidney, all of which were men. Mean patient age was 33.5 years, mean BMI 32.25 kg/m2, mean surgery duration 125 minutes, mean blood loss 55 ml, and mean hospital stay 2.75 days. The stone-free rate was 100 %. Blood loss and age, blood loss and stone size, and BMI and surgery duration were significantly correlated. Conclusions: Based on our experience, transperitoneal laparoscopic pyelolithotomy is an excellent alternative for treating kidney stones in patients with horseshoe kidney.
