Split prepuce in situ onlay hypospadias repair: 17 years of experience.

PURPOSE: We report our 17-year experience using split prepuce in situ onlay hypospadias repair, including long-term followup of the first 100 patients initially reported on in 1998. MATERIALS AND METHODS: We identified 421 patients who underwent in situ onlay repair. Charts were retrospectively reviewed to determine preoperative management, intraoperative details and complications. RESULTS: In situ onlay repair was used to repair glanular hypospadias in 22 cases (5.2%), coronal hypospadias in 184 (43.7%), distal shaft hypospadias in 152 (36.1%), mid shaft hypospadias in 51 (12.1%), proximal shaft hypospadias in 7 (1.6%) and hypospadias in the penoscrotal region in 5 (1.2%). Repair was successful with 1 procedure in 376 patients (89.4%), which increased to 99.8% after a second procedure. Complications were defined as any problem that gave the surgeon or family reason for concern. Functional complications requiring reoperation occurred in 45 patients (10.6%). Minor complications requiring simple procedures or early postoperative evaluation occurred in 17 patients (4%). Concerns not requiring intervention occurred in 27 patients (6.4%). There were no urethral strictures. Three patients (0.7%) were lost to followup. Repair is pending in 1 patient. CONCLUSIONS: In situ onlay repair preserves the urethral plate and allows the formation of a well vascularized flap with adequate tissue to completely cover the neourethra, resulting in a low rate of major complications. With longer followup, inclusion of more mid shaft repairs and expansion to more proximal degrees of hypospadias our complication rates are higher than previously reported but there have been no urethral strictures in 17 years of experience. Since complications present at a median of 158 days (mean 570) after the procedure, long-term followup is indicated.

Management of high grade renal trauma: 20-year experience at a pediatric level I trauma center.

PURPOSE: In the last 20 years the management of high grade, blunt renal trauma at our institution has evolved from primarily an operative approach to an expectant nonoperative approach. To evaluate our experience with the expectant nonoperative management of high grade, blunt renal trauma in children, we reviewed our 20-year experience regarding evaluation, management and outcomes in patients treated at our institution. MATERIALS AND METHODS: We retrospectively studied all patients sustaining renal trauma between 1983 and 2003. Medical records were reviewed for mechanism of injury, assigned grade of renal injury, patient treatment, indications for and timing of surgery, and outcome. Injuries were categorized as either low grade (I to III) or high grade (IV to V). RESULTS: We reviewed the medical records of 164 consecutive children who sustained blunt renal trauma between 1983 and 2003. A total of 38 patients were excluded for inadequate information. Of the remaining 126 children 60% had low grade and 40% had high grade renal injuries. A total of 11 patients (8.7%) required surgical or endoscopic intervention for renal causes, including 2 for congenital renal abnormalities and 1 for clot retention. Eight patients (6.3%) required surgical intervention for isolated renal trauma, of whom 2 (1.6%) required immediate surgical intervention for hemodynamic instability and 6 (4.8%) were treated with a delayed retroperitoneal approach. Only 4 patients (3.2%) required nephrectomy. All patients receiving operative intervention had high grade renal injury. CONCLUSIONS: Initial nonsurgical management of high grade blunt renal trauma in children is effective and is recommended for the hemodynamically stable child. When a child has persistent symptomatic urinary extravasation delayed retroperitoneal drainage may become necessary to reduce morbidity. Minimally invasive techniques should be considered before open operative intervention. Early operative management is rarely indicated for an isolated renal injury, except in the child who is hemodynamically unstable.
