Surgical treatment for prostatic utricle cyst in children: A single-center report of 15 patients.

OBJECTIVES: To report our single-center experience of the management of children with prostatic utricle cysts. METHODS: We retrospectively analyzed 15 children who were incidentally found to have a prostatic utricle cyst and were admitted to our department between October 2013 and August 2020. Clinical characteristics and management were collected and catalogued. RESULTS: Recurrent genitourinary tract infections were the most frequent complaint, and two-thirds of patients also had hypospadias. A connection between the posterior urethra and the prostatic utricle cyst was found in all cases. Two patients directly had their progressively enlarging prostatic utricle cyst resected laparoscopically. Endoscopic techniques were used in 13 patients, two of whom underwent laparoscopic excision for repeated symptoms. The mean (range) follow-up period was 34.9 (2-82) months. No recurrences were observed in four patients who underwent prostatic utricle cyst excision and eight patients who received endoscopic treatment. Three patients had recurrent symptoms after endoscopic treatment and were managed by nonsurgical treatment. CONCLUSIONS: Prostatic utricle cyst is a rare disease which can cause recurrent genitourinary tract infections. Extra attention should be paid to evaluation for prostatic utricle cyst in children with external genital anomalies. Retrograde urethrogram and magnetic resonance imaging are useful tools with which to distinguish prostatic utricle cyst from other cystic lesions that are located in the midline pelvis in male patients. Individualized treatment is appropriate when considering fertility preservation, recurrences and malignancy. Laparoscopic excision is feasible for symptomatic and large prostatic utricle cyst. Regular long-term monitoring is recommended for all patients with prostatic utricle cyst.

Laparoscopic radical excision of urachal remnants with recurrent infection in infants.

PURPOSE: To evaluate the usefulness of laparoscopic surgery in the management of urachal remnants with recurrent infection in infants. PATIENTS AND METHODS: Eight infants (mean age 9.6 months, range 2-16 months) underwent laparoscopic excision of urachal remnants with recurrent infection between June 2006 and December 2008. During the same period, 10 infants (mean age 13.2, range 4-17 months) underwent open surgery for the same condition. The laparoscopic surgery was performed transperitoneally by using three ports. The urachal remnant was dissected from the umbilicus to the bladder dome and then removed completely. RESULTS: Immediate complications did not develop in any patient. Blood loss, hospital stay, and operative time with laparoscopic surgery were less than those with open surgery. Recurrence did not develop in any patient who underwent laparoscopic surgery, while it did develop in one patient who underwent open surgery. CONCLUSION: The laparoscopic approach appears to be a safe and effective alternative to open surgery in the management of urachal remnants with recurrent infection in infants.

Long-term influence of prepubertal testicular torsion on spermatogenesis.

PURPOSE: To study the influence of prepubertal unilateral testicular torsion on spermatogenesis postpubertally. METHODS: Sixty prepubertal SD male rats were divided into 6 groups. In each group, animal suffered different courses of unilateral testicular torsion including sham operation, 2- and 6-hour-long torsion, and permanent torsion. Salvia miltiorrhiza was injected as a remedy to release the I/R injury in the 2- and 6-hour-long torted groups. Postpubertally, the percentage of DNA content of haploid cells in the testes was determined individually. RESULTS: The percentage of haploid cells in the sham operation group was 76.5+/-1.9%. The number decreased in every other group (p<0.01). Comparing with the same course of torsion, Salvia miltiorrhiza injection could improve the percentage of haploid cells (p<0.01). In the permanent unilateral testicular torted group, the percentage was nearly zero (0.4+/-0.2%). CONCLUSIONS: Prepubertal unilateral testicular torsion induces decreased spermatogenesis postpubertally. The result takes place in the bilateral testes. Salvia miltiorrhiza, as an antioxidant remedy, could relieve the injury which manifests improved spermatogenesis.

Bilateral intrarenal pelvis Wilms' tumor with fibroepithelial polyp.

Intrarenal pelvis Wilms' tumor is rare in children. A case of a 28-month-old boy with bilateral intrarenal pelvis Wilms' tumor associated with a fibroepithelial polyp is reported in this article. The tumor was evaluated by ultrasonography, computed tomography, and intravenous pyelography. The boy underwent bilateral renal pelviotomies. Now he is being treated and followed up by pediatric oncologists.
