Skin graft for 2-stage treatment of severe hypospadias: back to the future?

PURPOSE: Despite the introduction of more refined surgical techniques, the optimal treatment of the most severe forms of hypospadias remains to be determined. Single stage procedures, whether with the use of flaps or grafts, have long been regarded as the best approach, although the complication rate is nonnegligible with all procedures. MATERIALS AND METHODS: We report the use of a 2-stage repair with preputial graft interposition and subsequent tubularization of the urethral plate applied it to all severe cases of hypospadias with significant chordee or small glans. RESULTS: Both stages of the procedure were completed in 34 patients. Complications in 8 cases (23.5%) included 4 glans disruption in 4, coronal grove fistula in 2, urethral diverticulum in 1 and urethral stenosis due to balanitis xerotica obliterans in 1. Two pinhole fistulas also occurred which closed spontaneously. No complete disruptions or postoperative hematomas/bleeding was noted. Cosmetic and functional outcome after a minimum followup of 1 month was optimal in all cases with a normally located "slit" meatus and straight penile shaft. CONCLUSIONS: Although the controversy between use of grafts and flaps will probably continue forever, we believe that our 2-stage approach should be considered as a valid alternative for the most severe forms of hypospadias. Long-term results appear to outnumber the necessity of a learning curve for appropriate graft manipulation

Impalpable testis and laparoscopy: when the gonad is not visualized.

The diagnostic accuracy of laparoscopy for impalpable testis is well recognized. However, in some cases, laparoscopic findings may be misleading, and a viable gonad may be missed with significant medico-legal implications. From January 1993 to December 2000, 202 patients with 219 impalpable testes were evaluated. In 95 cases, the gonad was immediately visualized, and in 5, the presence of a testis was documented by inserting the scope into the processus vaginalis. In the 119 remaining cases, no gonad was seen while entering the abdomen with the laparoscope. All patients with documented vas and vessels exiting the inguinal ring were surgically explored. Ten testes were found, 8 ectopic, with significant changes in shape and position, and 2 were canalicular. In the absence of hormone stimulation, no testes were found while exploring patients with cord structures coursing a closed inguinal ring and with contralateral hypertrophy. In 1 patient with absent vas and vessels, the testis was found at the lower renal pole while removing a dysplastic kidney. Despite technical refinements and an increase in clinical practice, a small percentage of viable testes may be missed with laparoscopic findings consistent with absent/vanished inguinal testis. Therefore, inguinal exploration is mandatory in all these cases
