BackgroundUrologic guidelines universally recommend increasing fluid intake for kidney stone prevention. Increased voided volume is thought to help reduce stone recurrence and severity, but supporting evidence is limited.Patients and MethodsNephrolithiasis outcomes and 24‐h urine data for patients from the Registry for Stones of the Kidney and Ureter (ReSKU), a registry of nephrolithiasis patients collected between 2015 and 2020, were retrospectively analysed. Outcome was stone events, either an office visit where a patient reports symptomatic passage of stones or surgery for stone removal.ResultsWe identified 450 stone patients with 24‐h urine and kidney stone outcome data. There was no significant difference in 24‐h voided volume between patients with one stone event and patients with two or more stone events. On multivariable logistic regression, after controlling for age, gender, BMI, and 24‐h sodium and creatinine per kilogram, no significant associations were found between voided volume and stone events. There was a statistically significant negative correlation noted between voided volume and stone events in calcium oxalate dihydrate stone formers (Spearman R = −0.42, p = 0.04), but not others.ConclusionsTwenty‐four‐hour voided volume was not associated with stone events in a large institutional cohort, and subset analysis reveals that some stone formers may benefit more from increased voided volume than others; identifying such patients represents a novel precision medicine opportunity.
A 48-year-old male with HIV/AIDS presented with an enlarging nodular lesion on the base of his penis. Histology revealed changes consistent with chronic viral infection and culture grew herpes simplex virus 2 (HSV-2). The lesion was refractory to valacyclovir and intralesional (IL) cidofovir therapy. Urology excised the mass and the defect was repaired primarily with good cosmetic result. Post-operative pathology confirmed HSV-2 despite the unusual appearance of the lesion consisting of nodular mass without gross ulceration.
Background: Prune belly syndrome (PBS) and congenital pouch colon (CPC) are rare congenital syndromes with a low incidence in the United States (U.S.) with most CPC cases being from India. In this case report, we describe, to the best of our knowledge, the first PBS variant and CPC patient in the U.S.
Case Presentation: A 30-year-old G2P0010 woman was referred to a tertiary center after an 18-week ultrasound showed a fetal abdominal mass. A prenatal MRI showed a dilated loop of bowel containing a mixture of urine and meconium, oligohydramnios, and a protuberant abdominal wall. Born at 37 weeks, the child’s physical exam was notable for a distended abdomen with thin abdominal musculature, non-palpable bilateral testes, no anal opening, and flat buttocks. Intra-operatively, a dilated cecum/ascending colon was noted with an abrupt change in caliber at the transverse colon, bilateral enlarged ureters, a left testis at the internal ring and no visualized right testis. A colostomy and mucous fistula were created 5 cm from the sigmoid pouch.
Conclusion: While most reported cases of CPC undergo single stage repair (one operation) at 1 day of life, our patient underwent the first procedure of a staged repair at 16 hours of life given his clinical instability at the time as well as his unknown urological anatomy in the setting of urinary obstruction. This case demonstrates the importance of fetal imaging, multidisciplinary approach at a tertiary care center, and reinforces a staged repair when necessary.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
