Occurrence of renal stones associated with this anomaly has been reported up to 20%. Due to the high insertion of the ureter into the renal pelvis, there is a relative impairment of renal drainage which increases the risk of stone formation. We did this review to assess the outcome of different management approaches to treat stones associated with this anomaly. METHODS A retrospective review of 144 patients with horseshoe kidneys over ten year period (2000-2010) was performed. Twenty five patients (17.5%) were found to have renal stones. Demographic data of these patients were collected in addition to laterality, method of treatment, serum creatinine levels and the outcome of stone management was reviewed. We excluded patients with non-functioning moieties, those with associated genitourinary anomalies, and those with renal impairment or incomplete data. RESULTS We included 21 patients, 13 males (62%) and 8 females (38%) with a mean age of 41 years (2-78). Mean serum creatinine was 60 mmol/L. Eleven patients (52%) had stones in the left compartment, while 6 patients (29%) had it on the right one and 4 patients (19%) had bilateral renal stones. Patients with stone size less than 8 mm (9 patients) were treated expectantly with hydration and alkalization and only one patient required endoscopic intervention. Six patients (28.5%) with stone size between 1cm and less than 2cm were treated successfully with shock wave lithotripsy (SWL) with placement of double J stents and 6 patients (28.5%) with stone size of more than 2 cm were treated successfully with percutaneous nephrolithotomy (PNL). No significant peri-operative complications were encountered after all procedures. CONCLUSIONS Indications, method of treatment and outcome of management of stones associated with horseshoe kidneys are comparable to those with normal kidney morphology. A tailored approach based on stone size is highly recommended. In our study if intervention was required, SWL showed good stone free rate if accompanied with ureteric stenting and PNL appeared to be highly effective in achieving high stone-free rate with minimal morbidities. © 2016FiguresReferencesRelatedDetails Volume 195Issue 4SApril 2016Page: e325 Advertisement Copyright & Permissions© 2016MetricsAuthor Information Abdulhakim Al Otay More articles by this author Osama Sarhan More articles by this author Ahmed Al Helaly More articles by this author Khalid Albedaiwi More articles by this author Mustafa Al Ghanbar More articles by this author Ziad Nakshabandi More articles by this author Ali Obeid More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
