Testicular health awareness in pubertal males.

PURPOSE: We examined the knowledge and understanding of male teenagers of the necessity for genital examination, and signs and symptoms of serious testicular pathology. Furthermore, current national guidelines for health education were reviewed to understand better the curriculum used by the educational system and to assess its effectiveness. MATERIALS AND METHODS: In 1998, a 5-question survey was administered privately and confidentially to male athletes before a sports physical examination. The athletes were 12 to 18 years old, attended middle or high school, and were sampled randomly. The National Health Education Standards benchmark for grades 9 through 11 was examined with specific attention to male self-health education standards. RESULTS: A total of 318 athletes responded revealing that 54% did not know why the genitals were examined on a sports physical examination, 45% did not use appropriate testicular protection and the majority did not respond appropriately to symptoms of serious testicular pathology. Despite the fact that 46% of respondents answered that checking for a hernia is reason for a genital examination there was no mention of tumor, infection or varicocele. Review of the benchmarks revealed no standards referring to a minimum understanding of anatomy or physiology. Generalized guidelines for high risk behaviors were provided without specific mention of testicular torsion, cancer, varicocele or sexually transmitted diseases. CONCLUSIONS: Young males are at higher risk for testicular torsion, cancer and varicocele than other age groups, and yet our population was universally unaware of these as a reason for genital examination. Furthermore, the majority did not respond appropriately to questions regarding serious testicular pathology. Review of national guidelines reveals poorly defined, nonspecific provisions for male self-health care. Therefore, we have developed a curriculum for male self-health to address this problem.

Prepubertal varicoceles.

OBJECTIVES: Varicoceles are rarely detected in prepubertal boys. In an effort to further determine the natural history of prepubertal varicoceles, we have reviewed our experience with prepubertal boys who had varicoceles. METHODS: Eleven patients with prepubertal varicoceles were seen. The majority of patients (9 of 11) were asymptomatic. The mean age was 10.8 years (range 6 to 12). Ten of 11 patients had left-sided varicoceles. All varicoceles were grade III except for one that was grade II. Four patients underwent varicocele ligation, 3 via the Ivanessevich approach and 1 via the Palomo approach. RESULTS: The 4 patients who underwent varicocele ligation (operative group) had a follow-up that ranged from 6 to 72 months (mean 27.2) and the 7 patients who were observed (nonoperative group) had follow-up that ranged from 17 to 84 months (mean 40.8). All patients in the operative group exhibited "catch-up" growth of the affected testicle (mean relative testicular size 47% to 84% at follow-up). The relative left testicular size in the nonoperative group had decreased by a mean of 16.8% from the time of presentation (100% to 83.2% on follow-up). CONCLUSIONS: We conclude that prepubertal boys should be screened in the standing position for the presence of varicoceles. Secondary causes should be excluded. Patients may ultimately require intervention as our initial experience suggests improved testicular growth with early surgical repair.

Contralateral reflux after unilateral ureteral reimplantation in patients with a history of resolved contralateral reflux.

PURPOSE: We determined the risk of contralateral reflux after unilateral ureteral reimplantation in patients with a history of resolved contralateral reflux. MATERIALS AND METHODS: We reviewed our experience with 53 children who underwent unilateral ureteral reimplantation for primary vesicoureteral reflux. RESULTS: Postoperative contralateral reflux occurred in 5 of 11 children (45%) with a history of bilateral reflux that had resolved preoperatively on the contralateral side and 4 of 42 (10%) with no history of contralateral reflux. CONCLUSIONS: Strong consideration should be given to performing bilateral ureteral reimplantation in children with unilateral reflux and a history of resolved contralateral reflux.

Ureterocalycostomy.

Ureterocalycostomy, although infrequently indicated, can be a most useful aid to the urologist who is facing a difficult reconstruction problem. The use of this technique to provide internal urinary drainage in 2 patients with long-term nephrostomy tube drainage is described. One patient had a solitary functioning kidney. A third patient, facing nephrectomy from blunt renal trauma, had the kidney saved by this procedure. The technique of ureterocalycostomy is discussed.

Reflux in complete duplication in children.

Reflux is the most common abnormality associated with complete ureteral duplication. Several authors have emphasized early surgical correction of reflux when it occurs in duplicated systems. because of a negligible success rate in non-operative therapy. Our practice has been to judge an orifice with reflux on its own merit, that is position, appearance and submucosal tunnel length. Realizing that this philosophy is not in total agreement with most of the literature on reflux in ureteral duplication we have reviewed 59 cases to ascertain whether our non-operative approach has justification. In this study early operation was elected in 61 per cent of those patients with reflux in association with total duplication. However, in 48 per cent of patients followed with non-operative surveillance reflux has either stopped spontaneously or is medically stable.
