bookPart Litíase urinária em crianças(2014) OLIVEIRA, Lorena Marçalo; DENES, Francisco Tibor- Modified Abdominoplasty for Patients With the Prune Belly Syndrome(2014) DENES, Francisco Tibor; LOPES, Roberto Iglesias; OLIVEIRA, Lorena Marcalo; TAVARES, Alessandro; SROUGI, MiguelOBJECTIVE To present the results of a new technique for abdominoplasty in patients with the Prune Belly syndrome (PBS). METHODS Since 1985, 46 children with PBS underwent surgical treatment that included urinary tract reconstruction (UTR), orchidopexy, and abdominoplasty. In 41 patients, we performed the abdominoplasty as follows: (1) fusiform longitudinal resection of the mid-abdominal skin and subcutaneous tissue, with preservation of the musculo-aponeurotic fascia (MAF) and umbilicus, (2) ellipsoid unilateral longitudinal incision of the MAF in the most weakened side of the abdomen, producing 2 flaps, with the umbilicus being kept intact in the widest flap, (3) after UTR and bilateral orchiopexy, suture fixation of the widest MAF layer to the inner side of the contralateral abdominal wall, creating an inner MAF layer, (4) lateral suture fixation of the other flap over the inner layer, creating an outer MAF layer with a buttonhole exposing the umbilicus, that is sutured to the outer layer, and (5) approximation of the skin edges with incorporation of the umbilicus in the suture. RESULTS Skin coaptation was excellent in all patients, and no trimming was necessary in incision extremities. There was no dehiscence or skin necrosis and all patients presented immediate improvement of the abdominal tonus and appearance. Further improvement with growth was observed in all except 4 patients, 2 requiring secondary abdominoplasties. CONCLUSION We conclude that this technique is applicable in all forms of weakened abdomen typical of PBS, even in asymmetrical cases, requiring only 1 MAF incision, with good cosmetic and functional results.

- Revascularization of Living-Donor Kidney Transplant With Multiple Arteries: Long-term Outcomes Using the Inferior Epigastric Artery(2014) ANTONOPOULOS, Ioannis M.; YAMACAKE, Kleiton Gabriel Ribeiro; OLIVEIRA, Lorena M.; PIOVESAN, Affonso C.; KANASHIRO, Hideki; NAHAS, Willian C.OBJECTIVE To study the safety and long-term outcomes of use of the inferior epigastric artery (IEA) for revascularization of small accessory kidney arteries (3 mm or less). MATERIALS AND METHODS Data of 602 living-donor kidney transplants were reviewed. Age was 37.4 +/- 15 years (range, 3-78 years). Multiple arteries were present in 98 kidneys (16.3%); of these, 83 (84.7%) had 2 and arteries and 15 (15.3%) had 3 arteries. In 21 kidneys (21.4%) with multiple arteries (group I [GI]), the IEA was used for reconstruction. Four (14.3%) had 3 arteries, and 17 (85.7%) had 2 arteries. In 77 patients (group II [GII]), the inferior accessory renal artery was reconstructed with a side-to-side or an end-to-side anastomosis to the main renal artery. Follow-up was 43.8 +/- 38.1 months (range, 1-124 months). The Fisher exact test and the 2-tailed t test were used for statistical analysis. RESULTS Delayed graft function occurred in 1 GI patient (4.8%) and in 5 GII patients (6.5%; P >.05). One partial renal infarction occurred in each group (4.8% vs 1.3%; P >.05). There was 1 urinary fistula in GI and 3 urinary fistulas and 1 ureteral stenosis in GII (P >.05). One graft (4.8%) lost function in GI and 5 (6.5%) in GII (P >.05). Eleven patients (53.4%) were hypertensive in GI and 53 (68.8%) in GII (P >.05). CONCLUSION The use of the IEA for revascularization of a living-donor kidney transplant with multiple arteries is safe and effective, yielding similar long-term outcomes compared with the standard technique. Use of the IEA avoids the risks of manipulation of the main renal artery. (C) 2014 Elsevier Inc.
