OBJECTIVES To evaluate the effects of lower pole calyceal anatomy on lower pole stone clearance after shock-wave lithotripsy (SWL). METHODS A total of 133 patients who had single lower pole radio-opaque stones treated with SWL alone and who became stone-free or had clinically insignificant residual fragments (CIRF) were included in the study. Pre-shock-wave lithotripsy intravenous urograms were used to determine the lower pole infundibular width and length, lower pole infundibulopelvic (LPIP) angle, caliceal pelvic height (CPH), and lower infundibular length-to-width ratio. In addition, to evaluate the relationship between LPIP and CPH, a more simple alternative measurement instead of LPIP angle, called the parenchyma-to-ureter distance (PUD), was suggested. The correlation between LPIP and PUD was then examined, and a good correlation was found between these values (P <0.000, r = 0.64). The PUD/CPH ratio was also calculated. RESULTS The stone-free rate was 62%. According to the cutoff points, the lower infundibular length-to-width ratio and PUD/CPH ratio were different in the stone-free and CIRF groups by univariate analysis but not by multivariate analysis. CONCLUSIONS None of the anatomic factors had a statistically significant effect in predicting the success of SWL in patients with lower pole stones. Nevertheless, evaluation of relationships between lower pole anatomic factors may offer some help in reaching a more accurate interpretation of lower pole stone clearance after SWL.

Gil-Vernet antireflux procedure has been carried out for 22 refluxing renal units (14 patients), yielding a positive outcome in all, with disappearance of refluxing in 94% of the renal units with grade II, III and IV vesicoureteral reflux. The efficiency and simplicity of the technique is emphasized.

A 110 x 70 x 60-mm hydatid cyst in the right kidney of a 5-year-old boy was treated using a laparoscopic approach. The renal hydatid cyst was not identified before the operation. There were no complications related to surgery and therapy. The child was under follow-up for 12 months and there was no evidence of recurrence on ultrasonography and computed tomography during this period. To our knowledge, this is the first case of renal hydatid cyst treated by laparoscopic approach in a child.
