Comparison of shock wave lithotripsy (SWL) and retrograde intrarenal surgery (RIRS) for treatment of stone disease in horseshoe kidney patients

Abstract

Objectives In this study it is aimed to compare the success and complication rates of SWL and RIRS in treatment of HSK stone disease.Materials and methods In this retrospective study data of 67 patients treated with either SWL (n=44) or RIRS (n=23) for stone disease in HSK between May 2003 to August 2014 was investigated. age, gender, stone size and multiplicity, stone free status, renal colic episodes and complication rates of the SWL and RIRS groups were compared.Results Mean age of the population was 42.5±8.2 (range: 16-78) years and mean stone size was 16.9±4.1 mm. SWL and RIRS groups were similar with regard to demographic characteristics and stone related characteristics. SFR of the SWL and RIRS groups were 47.7%(21/44 patients) and 73.9% (17/23 patients) respectively (p=0.039).Renal colic episodes were observed in 3 and 16 patients in the RIRS and SWL groups respectively (p=0.024). No statistically significant complications were observed between the SWL (8/44 patients) and RIRS (4/23) groups (p=0.936).Conclusions In HSK patients with stone disease, both SWL and RIRS are effective and safe treatment modalities. However RIRS seems to maintain higher SFRs with comparable complication rates.

Changing trends in the endourological management of urolithiasis in anomalous kidneys

“…Variable success rates in the management of stones in anomalous kidneys have been reported for ESWL, ranging from 31% to 100% . In the present series, only three patients with a horseshoe kidney underwent ESWL.…”

Outcomes of ureteroscopy for stone disease in anomalous kidneys: a systematic review

“…The mean operative time was 61.3 min (range 14-185 min). While six studies report a post-operative stent placement in all of their patients [13,14,19,21,22,26], in the remaining studies this varied from 46.2 to 84% and was at the surgeon's discretion [15][16][17][23][24][25]. The mean hospital stay across studies was 1.7 days (range 0.5-9 days) ( Table 4).…”

Management of upper urinary tract calculi in crossed fused renal ectopic anomaly

“…RIRS is to be an alternative to PCNL for the management of large renal calculi (≤3.5 cm) (26) and has been demonstrated as a safe and effective measure for treating stone disease in patients with horseshoe kidneys (27). A study by Resorlu et al (14) reported a 28-year-old male with calyceal stones in his ectopic kidney who underwent RIRS with a good outcome.…”
