Mini-percutaneous nephrolithotomy.

Abstract

Standard percutaneous nephrolithotomy is highly effective for the removal of renal calculi. However, significant morbidity has been associated with this procedure. Consequently, many urologists inappropriately defer to a less effective procedure to reduce patient morbidity. This practice may increase the total number of procedures needed for treatment and result in a substantial increase in health care costs. Mini-percutaneous nephrolithotomy using a 13F ureteroscopy sheath is described to reduce the morbidity associated with standard percutaneous nephrolithotomy while maintaining its efficiency and effectiveness for stone removal. The indications and technique for mini-percutaneous nephrolithotomy and our results are summarized.

Direct comparison of radiology and nuclear medicine cystograms in young infants with vesico-ureteric reflux.

OBJECTIVE: To determine the sensitivity of the direct radionuclide cystogram (DRC) in detecting vesico-ureteric reflux compared with the micturating cysto-urethrogram (MCU) in the same initial setting, in infants younger than one year. PATIENTS AND METHODS: The results from the dual cystograms of 62 refluxing infants < 1 year old (mean 0.58) were compared. Results from same-day renal scintigraphy with dimercaptosuccinic acid (DMSA) in 60 of the 62 infants were also compared with the reflux grades. RESULTS: Reflux was detected in 105 units, 96 detected on the DRC and 47 on the MCU, representing a sensitivity of 91% and 45%, respectively. The DRC missed half of grade 1, 20% of grade 2 and 6% of grade 3 reflux. Reflux at low bladder filling rates (DRC) represented 40% of all reflux units, and a half (52%) of scarred renal units detected by DMSA scintigraphy. CONCLUSIONS: In young infants the MCU may fail to detect significant reflux and the DRC may fail to detect the lesser grades. The combination of both cystograms in the initial investigation of reflux provides more comprehensive information.

Successful in utero endoscopic ablation of posterior urethral valves: a new dimension in fetal urology.

Fetal lower urinary tract obstructive uropathy, when associated with oligohydramnios, is usually associated with a poor outcome. We present a case of successful in utero endoscopic ablation of posterior urethral valves in which the infant survived the neonatal period without evidence of renal dysplasia. The role, indications, and potential benefits of this novel technique are discussed.
