Utility of preoperative urine cultures and cystoscopies before ureteral reimplantation in pediatrics.

BACKGROUND: Ureteral reimplantation remains the primary surgical method used for patients with vesicoureteral reflux (VUR). Cystoscopy is commonly performed first to visualize anatomy and rule out possible abnormalities. Urine cultures may also be obtained. The objective of this study is to evaluate the prudency of preoperative urine cultures and cystoscopies in pediatric patients undergoing ureteral reimplantation. METHODS: Pediatric urologists were surveyed regarding collecting urine cultures in asymptomatic patients and cystoscopies before reimplantation. A retrospective review was also conducted of patients who underwent ureteral reimplantation for VUR between March 2018 and April 2021 at Cook Children's Medical Center. RESULTS: When physicians were asked the frequency they obtain urine cultures before reimplantation on asymptomatic patients, 36% said "never" and 38% said "always." Regarding cystoscopy, 53% said "never" and 32% said "always." Inclusion criteria were met by 101 patients. Cystoscopies were performed in 46 patients and never altered the reimplantation. There were 20 preoperative, 90 intraoperative, and 61 postoperative urine cultures. Complications were associated with positive cultures of urine collected intraoperatively and postoperatively only. CONCLUSION: Cystoscopies and asymptomatic urine cultures obtained before ureteral reimplantation provide no additional benefit while increasing cost for patients' families. Further research is needed to thoroughly identify the prudency of such practices in ureteral reimplantation for VUR.

Giant Multilocular Prostatic Cystadenoma in a 14-Year-Old Male: A Case Report of a Pediatric Pelvic Mass.

Giant multilocular prostatic cystadenoma (GMC) is an extremely rare, benign tumor seen in both adult and pediatric males. The neoplasm originates from prostatic tissue and is typically found within the rectovesical pouch, varying in both size and morphology. Microscopically, GMC contains both glandular and cystic prostatic tissue lined by cuboidal and columnar epithelium. Symptoms often arise once the pelvic mass begins to obstruct the surrounding structures and organs, although invasion into surrounding tissue is unlikely. Common symptoms include abdominal pain, urinary retention, and dysuria. The standard treatment for GMC is surgical removal of the mass with good outcomes and only 1 known case of recurrence. Here we present the case of a 14-year-old male with GMC-the youngest patient reported to date-who presented with abdominal pain, difficulty voiding, and hydroureteronephrosis.

Circumcision controversies.

Despite its long history and common practice, circumcision remains a controversial procedure. This article reviews the history of this operation, examines the controversy that surrounds it, and emphasizes the performing practitioner's responsibility to the patient and his family in guiding them through the complicated decision making surrounding newborn circumcision.

Lack of usefulness of positioned instillation of contrast cystogram after injection of dextranomer/hyaluronic acid.

PURPOSE: Positioned instillation of contrast cystograms have been touted as possibly being more sensitive than standard cystograms for evaluation of vesicoureteral reflux. We performed positioned instillation of contrast cystograms intraoperatively, immediately after the injection of dextranomer/hyaluronic acid to treat vesicoureteral reflux, to determine whether they might be predictive of operative success and obviate the need for the standard postoperative voiding cystourethrogram, which is usually performed at 3 months. MATERIALS AND METHODS: Patients with vesicoureteral reflux and no confounding conditions were treated with dextranomer/hyaluronic acid and subsequent positioned instillation of contrast cystogram while under the same anesthesia between November 2003 and March 2005. The results of this intraoperative cystogram were compared to the results of the postoperative voiding cystourethrogram performed 3 to 4 months later. RESULTS: A total of 61 patients met the inclusion criteria and underwent positioned instillation of contrast cystogram after dextranomer/hyaluronic acid injection. Only 53 patients (86 ureters) completed the necessary postoperative evaluation. Positioned instillation of contrast cystogram added 4 minutes to the procedure and required about 4 seconds of fluoroscopy per ureter evaluated. The overall success rate for correcting reflux was 84% (72 of 86 ureters cured). None of the 14 ureters with persistent postoperative reflux was identified by intraoperative cystogram, and 3 patients were misidentified as having reflux despite cure confirmed postoperatively. Intraoperative positioned instillation of contrast cystogram was predictive of treatment failure 0% of the time (sensitivity 0%). There were no complications. CONCLUSIONS: Positioned instillation of contrast cystogram performed immediately after injection of dextranomer/hyaluronic acid was not useful in predicting which patients would have persistent reflux postoperatively. Patients are best served with the extant protocol of conventional cystography 3 to 4 months postoperatively.

Vesicoureteral reflux in the Hispanic child with urinary tract infection.

PURPOSE: Hispanic individuals have become the largest minority in the United States. Prior studies of minorities revealed real differences in vesicouretal reflux rates between white and black Americans. We studied the incidence of reflux in the Hispanic population to see if the reflux rate was different from that of the white population. MATERIALS AND METHODS: We reviewed the results of voiding cystourethrograms performed in Hispanic children as our normal screening for reflux and compared them to voiding cystourethrograms results in a group of white children. The children were identified as Hispanic or white by their parents on an intake form. RESULTS: Of the Hispanic children 27% had vesicoureteral reflux on voiding cystogram, while 32% of the white children had vesicoureteral reflux. CONCLUSIONS: Hispanic patients presenting with the first urinary tract infection seem to be afflicted with vesicoureteral reflux as often as their white contemporaries. Hispanic children should be screened as aggressively as white children when they present with urinary tract infections.
