Percutaneous nephrostolithotomy: predictors of length of stay.

Purpose: Percutaneous nephrostolithotomy (PNL) is commonly used to treat patients with complex renal calculi. A goal at our medical center is to discharge patients home less than 24 hours after PNL. We performed a study to determine factors that caused patients to be hospitalized longer than this period.

Ileal ureter substitution: a contemporary series.

Objectives: To review our contemporary experience with ileal ureter reconstruction. Despite advancements in surgical technology and technical expertise, ureteral injuries continue to occur. These injuries can be extensive, and ileal ureter reconstruction may be necessary.

The impact of cystinuria on renal function.

Purpose: Patients with cystinuria frequently have recurrent renal calculi and may subsequently require multiple stone removing procedures during their lifetime which could have an impact on overall renal function. We determined the potential impact of cystinuria and cystine stone formation on the level of renal function compared to calcium oxalate stone formers.

Materials And Methods: Clinical data on 40 cystinuric patients followed at 2 medical centers and 45 such individuals in a large stone population data base were analyzed.
