Consequences of bilateral cryptorchidism in adults.

Bilateral cryptorchidism treatment results are often shadowed by the majority of unilateral cases. We report the long-term follow-up results of boys treated for bilateral cryptorchidism during childhood. Patients treated in two main paediatric surgery centres were selected from medical registries and invited for a clinical examination including scrotal ultrasound, salivary testosterone measurement and a semen sample. Thirty-six men (38.3%) replied to the written invitation, and 21 agreed to be examined. The mean age at orchidopexy was 74 months (range 24-138). Sperm count was 0.42 × 106 (SD ± 0.64 × 106 ) ml-1 . The correlation between total testicular volume and total sperm count was statistically significant (r = 0.481; P = 0.032). These results show that surgical treatment of bilateral cryptorchidism after the age of 2 years does not prevent infertility. Sperm count and endocrine evaluation advocated after the treatment of bilateral cryptorchidism in all adult patients.

The long-term followup of 33 cases of true hermaphroditism: a 40-year experience with conservative gonadal surgery.

PURPOSE: Little is known about long-term outcomes of conservative gonadal surgery in true hermaphroditism. We present our experience with evaluation and treatment of a large series of children with this rare form of ambiguous genitalia, focusing on gonadal structure and function before and after conservative gonadal surgery. MATERIALS AND METHODS: We retrospectively reviewed 33 consecutive patients with histologically confirmed true hermaphroditism treated at the Hopital des Enfants-Malades between 1965 and 2005. RESULTS: The most common karyotype of true hermaphrodites was 46,XX, constituting 82% of our series. The frequency of finding the SRY gene in 46,XX cases was 35%. Ovotestis was the most frequent finding (65%) and testis the rarest (9%). Ovarian tissue was more often found on the left side, and testicular tissue on the right side (p <0.05). Proper gonadal tissue was preserved in 28 cases. No gonadal tumors were detected during followup. Ovarian tissue remained normal, while testicular tissue gradually developed signs of dysgenesis in all biopsied cases, confirmed by endocrinological studies. However, testosterone production remained satisfactory in the majority of cases during followup. CONCLUSIONS: Diagnosis of true hermaphroditism is well defined and the condition can be recognized even prenatally. Conservative gonadal surgery is the procedure of choice after a diagnosis of true hermaphroditism. Continued followup is necessary because of the multiple psychological, gynecological and urological problems encountered postpubertally by these patients.

Recognition of bladder instability on voiding cystourethrography in infants with urinary tract infection.

PURPOSE: We evaluate voiding cystourethrography as a method for identifying bladder instability in infants. MATERIALS AND METHODS: Cystometry was combined with voiding cystourethrography in 79 male and 64 female infants with first time urinary tract infection. Bladder wall irregularity, elongation of bladder shape, and filling of the posterior urethra were transient radiological signs occurring during bladder filling and were considered to reflect bladder instability. A pediatric radiologist looked for these signs on all 480 films exposed during bladder filling. The results were correlated to simultaneous detrusor pressure recordings. The analysis was repeated independently by a urologist to evaluate the reliability of the radiological signs used. RESULTS: The sensitivity and specificity were both 90% in the evaluation of radiological signs of bladder instability. Filling of the posterior urethra was the least frequently reported radiological sign, which was seen at 53% of unstable contractions. However, when this sign was reported, instability was usually correctly detected (85%). Evaluation accuracy had improved with increasing numbers of noted signs per film. This accuracy had included 29%, 67% and 91% of unstable contractions that were correctly diagnosed when 1, 2 or 3 signs were noted, respectively. The number of noted signs was positively related to the strength of the unstable detrusor contraction. Urologist evaluations had similar results to the radiologist, although the sensitivity was somewhat lower (79% and 90%, respectively). CONCLUSIONS: Unstable detrusor contractions could be identified in infants by evaluation of radiological signs on voiding cystourethrography. Findings of bladder wall irregularity, elongation of bladder shape and filling of the posterior urethra indicated unstable detrusor contraction. The more such findings are observed, the stronger the indication.
