Transabdominal pelvic sonography in the preoperative evaluation of patients with congenital adrenal hyperplasia.

PURPOSE: We assessed the clinical value of transabdominal pelvic sonography in the preoperative evaluation of patients with congenital adrenal hyperplasia (CAH) who required feminizing genitoplasty. METHODS: From 1987 to 1998, 31 patients with female pseudohermaphroditism due to CAH underwent feminizing genitoplasty. The median age of the patients was 9 months (range, 1-18 years). Radiologic evaluation performed before surgical reconstruction included retrograde genitography in the first 10 patients and sonographic examination in all 31 patients. Imaging was used to evaluate the anatomic positions and the length of the vagina, whether the junction of the vagina and the urogenital sinus occurred distal or proximal to the pelvic floor, and the presence of internal genitalia. RESULTS: Abdominal sonography identified internal female genitalia in all 31 patients, identified the anatomic shape and position of the vagina in 30 patients (97%), and confirmed the site of communication between the vagina and the urogenital sinus relative to the pelvic floor in 28 patients (90%). Sonographic findings were confirmed by intraoperative panendoscopy. Genitography was less useful than sonography, identifying the site of communication between the vagina and urogenital sinus in only 6 (60%) of 10 patients. CONCLUSIONS: In patients with CAH undergoing vaginal reconstruction, sonography provides adequate information about the anatomy of the vagina and urogenital sinus for surgical decision-making.

Laser prostatectomy. Long-term follow-up of 303 patients.

OBJECTIVE: This retrospective study was undertaken to evaluate results and complications in 303 patients with symptomatic bladder outlet obstruction due to benign prostatic hyperplasia (BPH) who underwent laser prostatectomy focusing on the long-term follow-up, 57 patients had a follow-up of more than 3 years. MATERIALS AND METHODS: A total of 303 patients were treated with the neodymium:YAG laser system for 1993 to 1997, of whom 57 patients were followed up for at least 3 years. All of the patients have been evaluated after 3 months, 6 months and 2 years. 57 patients were evaluated after 3 years. Pre- and postoperative American Urological Association (AUA) symptom score, uroflowmetry (UF), and immediate and long-term complications were assessed. RESULTS: The mean AUA symptom scores of 303 patients decreased over the 24 months follow-up from 16.9 to 7.6. In 57 patients after 36 months the mean AUA symptom score was 7.1. The mean maximal UF increased over the 24 months from 9 to 14.1 cm3/s in 303 patients. In 57 patients at 3 years the mean UF was 13. 9 cm3/s. The overall complications of 303 patients included two perforations of the bladder wall and two perforations of the prostatic capsule. Six (1.9%) patients had postoperative febrile UTI and 28 (9.2%) patients had acute urinary retention after catheter removal. Early bleeding occurred in 3 (0.9%) patients, late bleeding in 8 (2.4%), 4 (1.2%) had urethral stricture, and 1 had stricture of the bladder neck. The overall reoperation rate for symptomatic residual tissue was 1.9% (6 patients). CONCLUSION: Neodymium:YAG laser ablation of prostate represents an efficacious surgical intervention for symptomatic bladder outlet obstruction due to BPH with minimal associated morbidity.

One-stage repair of hypospadias--experience with 856 cases.

OBJECTIVES: 856 cases of hypospadias, operated over a period of 7 years, using various methods of one-stage repair, are reviewed in order to assess their functional and cosmetic results and their rate of complications. PATIENTS AND METHODS: 856 boys with an average age of 3.5 years were classified according to the classification proposed by Duckett (anterior, middle and posterior hypospadias). Magpi, Mathieu's (flip-flap technique) and pedicled flaps tubularized or as onlay were utilized, depending upon the severity of the anomaly. RESULTS: Satisfactory functional and cosmetic results without complications were obtained in 736 cases (85.9%). We had early complications with 72 cases consisting of 64 fistulas (7. 5%) and 8 cases of breakdown (0.93%), and 48 cases of delayed complications consisting of 26 meatal retractions (3.1%) and 22 cases of meatal stenosis (2.5%).

[Severity of testicular varicocele and sperm cell ultramorphologic characteristics].

Ultramorphologic characteristics of sperm cells found in infertile men with varicoceles were compared with the severity of the varicocele. Classification of varicoceles into mild, moderate or marked was determined by spermatic vein diameter and degree of blood reflux. These were evaluated by high resolution duplex sonography. There were no statistical differences between the 3 grades of varicocele severity with regard to abnormalities in the subcellular organelles of the acrosome, karyoplasm, and skeleton of spermatozoal heads, or in the axoneme, outer dense fiber and skeleton of sperm cell tails. The only abnormal ultramorphologic features found to be significant among the 3 groups were differences in the frequencies of karyoplasm agenesis, and of partial agenesis, malformation and degeneration of the acrosome in sperm cell heads. However, these features could not be related to grade of severity and therefore, no ultramorphologic severity pattern could be detected. Thus, no varicocele beneficial score based on grade of severity and sperm cell ultramorphology can be suggested for clinical use.

[Ultramorphological changes in sperm cells of infertile men with testicular varicocele].

The ultramorphological characteristics of sperm cells of infertile men with testicular varicocele were evaluated. There was an increased frequency of abnormal changes within their spermatozoa as compared to fertile men. The abnormalities included agenesis, partial agenesis, malformation and degradation of the subcellular organelles of the heads and tails of the sperm cells. These findings suggest the use of these characteristics as a part of a "varicocele score" to determine those who would benefit from varicocelectomy in the treatment of their infertility.
