Randomized Controlled TrialEfficacy of intravesical ropivacaine injection on urinary symptoms following ureteral stenting: a randomized, controlled study.
Previous studies suggest that intravesical administration of nonsteroidal anti-inflammatory drugs may reduce the troublesome voiding symptoms and pain related to ureteral stenting. The objective of this study was to investigate the effectiveness of a long-acting local anesthetic, ropivacaine, injected submucosally into the bladder to control ureteral stent-associated symptoms. ⋯ Our preliminary investigation with intravesical injection of ropivacaine before ureteroscopic surgery demonstrated trends toward decreased pain and voiding symptoms in this small-sample study. Inclusion of a larger sample should definitively address the effectiveness of intravesical ropivacaine and its impact on stent-related symptoms.

Randomized Controlled Trial Comparative StudyA randomized comparison of tubeless and standard percutaneous nephrolithotomy.
We present a randomized study of tubeless or nephrostomy-free percutaneous nephrolithotomy (PCNL), a modification of the standard technique, compared with standard PCNL to evaluate the role of tubeless PCNL in minimizing postoperative discomfort and reducing duration of hospital stay. ⋯ Nephrostomy-free or tubeless PCNL reduces postoperative urinary leakage and local pain related to the drainage tube. It also minimizes hospital stay; the majority of patients were discharged from the hospital in fewer than 24 hours.
