Randomized Controlled Trial Comparative Study Clinical TrialIs ureteral stenting necessary after uncomplicated ureteroscopic lithotripsy? A prospective, randomized controlled trial.
We conducted a prospective, randomized controlled study to investigate the advantages and disadvantages of ureteral stenting after ureteroscopic lithotripsy. ⋯ After uncomplicated ureteroscopic electrohydraulic lithotripsy patients without ureteral stenting tend to have similar renal function recovery and satisfactory pain reduction with less irritative symptoms compared to those treated with a ureteral stent. We suggest that it is not necessary to place a ureteral stent routinely after uncomplicated ureteroscopic electrohydraulic lithotripsy for stones smaller than 1 cm.

Ultrasound grade of hydronephrosis and severity of renal cortical damage on 99m technetium dimercaptosuccinic acid renal scan in infants with unilateral hydronephrosis during followup and after pyeloplasty.
We performed ultrasonography and (99m)technetium dimercaptosuccinic acid (DMSA) renal scan in infants with unilateral hydronephrosis during followup and after pyeloplasty to examine the correlation of ultrasound hydronephrosis grade with the severity of renal cortical damage and assess the recovery of renal function in the obstructed kidneys after surgery. ⋯ Ultrasound grading of hydronephrosis correlates with the severity of cortical damage or the decrease in renal function on DMSA renal scan. Differential renal function on DMSA renal scan may be a useful and less invasive tool for determining surgical indications and examining changes in renal function after surgery.
