RESUMO
Introducción: La nefrectomía laparoscópica en niños se ha convertido en una alternativa razonable a la nefrectomía abierta y ha sustituido a la cirugía abierta en muchas enfermedades renales. El objetivo de nuestro estudio es evaluar los procedimientos videolaparoscópicos transperitoneales en las enfermedades renales benignas en comparación con el abordaje quirúrgico abierto. Pacientes y método: 34 niños de edades comprendidas entre los 17 días y los 15 años (media, 6, 14 años) fueron divididos en dos grupos de nefrectomía; el primero fue sometido a nefrectomía videolaparoscópica transperitoneal y estaba compuesto por 21 pacientes (12 mujeres y 9 varones) con edades comprendidas entre los 2 meses y los 15 años (media, 7, 42 años). El segundo grupo fue sometido a nefrectomía abierta y estaba compuesto por 13 pacientes (6 mujeres y 7 varones) con edades comprendidas entre los 17 días y los 11 años (media, 3,91 años). Los grupos se compararon respecto al tiempo de anestesia, el tiempo operatorio, la duración de la estancia hospitalaria, el dolor postoperatorio y el tiempo de reinstauración de la ingesta oral. También se evaluaron las complicaciones acorto y largo plazo. El análisis estadístico se llevó a cabo mediante la prueba de la t de Student, y se estimó significativo el valor de p < 0,05. El Comité de Ética Científica de nuestra institución aprobó previamente el estudio. Resultados: Se observaron diferencias estadísticamente significativas sólo en cuanto a la variable duración de la estancia hospitalaria. Ningún caso del grupo a laparoscopia se convirtió en cirugía abierta. No se observaron complicaciones inmediatas ni tardías. La pérdida de sangre fue insignificante y no fue necesario administrar transfusiones. Conclusiones: Según nuestra experiencia, la nefrectomía videolaparoscópica transperitoneal presenta resultados similares a los de la nefrectomía abierta, excepto en lo que respecta al tiempo de hospitalización (AU)
Introduction: Laparoscopic nephrectomy in children has become a reasonable alternative to open nephrectomy and has replaced open surgery for many renal diseases. The purpose of our study is to evaluate transperitoneal videolaparoscopic procedures in renal benign diseases in comparison to an open surgery approach. Patients and methods: 34 children aged between 17 days and 15 years old (mean 6.14) were divided into two groups in order to be submitted to nephrectomy. The first one underwent transperitoneal videolaparoscopic nephrectomy and was composed by 21 patients aged from 2 months to 15 years (mean 7.42), from which 12 were females and 9 males. The second group was submitted to open nephrectomy and was composed by 13 patients aged from 17 days to 11 years (mean 3.91), 6 females and 7 males. The groups were compared regarding anesthesic time, operative time, length of hospital stay, postoperative pain and time of reintroduction of oral intake. Short and long term complications were also evaluated. Statistical analysis was performed by Student t-test with the level of significance set at P < 0.05. The study was previously approved by the Committee on Ethics in Research of our institution. Results: Significant statistical difference was observed only for the variable length of hospital stay. No laparoscopy group case was converted to open surgery. There was no immediate or late complication. Blood loss was negligible and no transfusion was required. Conclusions: In our experience, transperitoneal videolaparoscopic nephrectomy has similar results to open nephrectomy, except for time of hospitalization (AU)

INTRODUCTION: Laparoscopic nephrectomy in children has become a reasonable alternative to open nephrectomy and has replaced open surgery for many kidney diseases. The aim of our study is to evaluate transperitoneal videolaparoscopic procedures in benign renal disease compared with the open surgical approach. PATIENTS AND METHODS: 34 children aged between 17 days and 15 years (mean, 6.14 years) were divided into two nephrectomy groups. The first underwent transperitoneal videolaparoscopic nephrectomy and was composed of 21 patients (12 female and 9 male) aged between 2 months and 15 years (mean, 7.42 years). The second group underwent open nephrectomy and was composed of 13 patients (6 female and 7 male) aged between 17 days and 11 years (mean, 3.91 years). The groups were compared for time of anaesthesia, operating time, length of hospital stay, postoperative pain and time to restore oral intake. Short and long term complications were also evaluated. Statistical analysis was performed by a Student's t test, with a p value < 0.05 being considered significant. The study was approved beforehand by the Scientific Ethics Committee in our institution. RESULTS: Statistically significant differences were observed only for the length of hospital stay. No cases in the laparoscopic group were converted into open surgery. There were no immediate or late complications. Blood loss was negligible and so it was not necessary to administer any transfusions. CONCLUSIONS: In our experience, transperitoneal videolaparoscopic nephrectomy has similar results to those of open nephrectomy, except for hospitalisation times.

To evaluate the rate of acute cellular rejection (ACR) and long-term results in different levels of anti-HLA sensitization, using noninduction or different induction therapies, 763 patients who underwent transplantation from January 1995 to December 2001 were evaluated: 213 patients received induction therapy, 71 received Thymoglobulin (Thymo), 66 Simulect, and 44 OKT3. Follow-up time was at least 1 year for all groups. The Simulect group included older recipients and the OKT3 group had more female patients. Simulect and OKT3 groups had more black patients; Thymo and OKT3 groups had more retransplantations. PRA was low in the noninduction group (mean, 7%) and about the same in the Simulect and Thymo groups (mean, 30%). OKT3 was the most sensitized group (mean = 59%). Dialysis during the first posttransplantation week was more frequent among the induction groups (43% vs 65%; P <.005). Fewer patients experienced rejection episodes in the Thymo group (20% vs 50%; P =.02). Patients were classified according to their level of sensitization, and the Thymo group showed the lower rejection rates in all levels (mean, 20%; P =.001). When analyzing PRA >50%, the Thymo group showed lower rejection rates (12% vs 50%; P =.02). At this level of sensitization, there was no significant difference on graft loss and death with a functioning graft. There was a trend to more cytomegalovirus (CMV) disease in the Thymo group (33% vs 23%; P =.08). Two PTLD were diagnosed, both in the noninduction group. Renal function was better in the Thymo group (1.3 mg/dL). In conclusion, Thymo showed lower ACR rates in all PRA groups. No significant differences in CMV infection, tumors, and patient survival were observed.

The use of bovine pericardium as a urethral patch to substitute a ventral segment of canine urethras was studied. Healing, epithelial growth, urethral permeability, fistulas, and calcification were analyzed. Thirty male mongrel dogs of medium and large size underwent resection of a ventral segment of the medial urethra measuring 2.0 x 0.5 cm, which was replaced with a bovine pericardium graft, treated with buffered glutaraldehyde and preserved in formaldehyde. Two running sutures of polygalactin 5-0 were applied, one on each side of the patch. The corpus spongiosum was closed with uninterrupted suture and the skin with interrupted suture of polygalactin 5-0. Six months later, the animals were examined and sacrificed under anesthesia. Retrograde urethrograms showed that the urethral healing was complete in six of the 30 animals, without stenosis, fistulas or dilations. Microscopic examination showed complete epithelization of these six urethras. The remaining 24 animals presented urethrocutaneous fistulas without stenosis, demonstrated by urethral catheterism using a 10-Fr plastic catheter. These data show that a successful urethral reconstruction of the penile urethra was possible in only 20% of the operated animals. Infection and leakage may be the cause of the urethrocutaneous fistulas present in 80% of cases. Further studies are necessary to determine whether such fistulas are avoidable. If they are, the bovine pericardium may well be an option in the treatment of urethral lesions in dogs.

OBJECTIVES: To analyse the incidence of diurnal incontinence (DI) and nocturnal incontinence (NI), the need for intermittent catheterization (IC),and the rate of ureteric obstruction (UO) among a group of men and women with ileal and colonic orthotopic neobladders in four countries. PATIENTS AND METHODS: In all, 138 patients (113 men and 25 women) had an orthotopic neobladder constructed after radical cystectomy for carcinoma. The mean(range) age was 61.3 (28-76) years and the follow-up 41 (6-144) months. All patients underwent surgery by experienced surgeons associated with the Confederation of American Urology. A retrospective evaluation was designed to review the functional results and the incidence of UO. The technique of orthotopic neobladder construction was at each surgeon's discretion. Various detubularized bowel segments were used, including ileum, colon or sigmoid. Patients were followed by chart reviews and personal interviews at 1, 3 and 6 months after surgery and then every 6 months, and were evaluated by a physical examination, urine analysis, cytology and renal ultrasonography. RESULTS: An ileal or colonic neobladder was constructed in 74 and 64 patients, respectively. Five (7%), 23 (31%), 10 (14%) and 14(9.6%) with an ileal neobladder developed DI, NI, IC and UO, respectively; the respective values for patients with a colonic neobladder were eight (12%), 19 (30%), seven (11%)and 15 (12%). Statistical analysis by Fisher's exact test showed no significant differences between the ileal and colonic neobladder groups or with gender. CONCLUSIONS: Using this specific protocol for evaluating many men and women with ileal and colonic orthotopic neobladders showed no significant differences in the incidence of DI, NI, IC or UO. Neobladders constructed from detubularized bowel, irrespective of bowel segment(s) used, can provide satisfactory diurnal results. A moderate incidence of NI and UO continue to be a problem.

OBJECTIVES: The objective of this study was to find HPV DNA incidence in women with CIN and normal women and in their respective partners, as well as the relation between the virus groups found in women with CIN or normal women and in their respective partners. METHODS: Partners of 30 women with CIN at several grades and of 60 normal women were prospectively assessed. In men, HPV search was performed by collecting samples through penile scraping for Hybrid Capture, followed by peniscopic evaluation and biopsy of acetowhite lesions. RESULTS: The presence of HPV DNA in male partners does not necessarily implicate the presence of HPV or even CIN in their female partners. CONCLUSIONS: If these results are confirmed by other authors, obtaining a peniscopy, a penile biopsy, and a HPV DNA search in partners that present with no clinical lesions, but in couples with women having CIN, would not be warranted.

STUDY DESIGN: Retrospective study. OBJECTIVE: To determine if spinal cord injuries due to gunshot wounds (GW) are associated with different bladder and sphincteric behavior compared to other trauma mechanisms. SETTING: Spinal injury center, Brazilian university hospital. METHODS: We retrospectively evaluated the records and urodynamic studies of 71 patients with spinal cord injury (SCI) referred to the Brazilian National Spinal Cord Injury Center over the year 2000, and compared the bladder-sphincteric pattern of patients with injuries caused by GW with those caused by other trauma mechanisms. RESULTS: The causes of SCI were (1) gunshot wounds (31 patients: 43.7%); (2) motor vehicle accidents (16 patients: 22.5%); (3) falls (16 patients: 22.5%) and (4) diving (three patients: 4.2%). In five patients (7.1%) the causes were unusual trauma mechanisms like stab wound (one patient) and direct trauma in vigorous sports (two patients) or fights (two patients). The levels of the injuries were cervical in 22 patients (31.0%), thoracic in 39 (54.9%) and lumbar in 10 (14.1%). Detrusor hyperreflexia with detrusor-sphincter dyssynergia was present in 65% of the patients overall and in 76% of the thoracic gunshot wounded. Areflexia occurred in 20% of the patients and in 16% of thoracic injured patients with gunshots. Detrusor hyperreflexia with detrusor-sphincter dyssynergia was the pattern encountered in 50% of the individuals suffering from SCI because of other mechanisms and areflexia was present in 35.8%. There was no statistical difference between GW patients and other mechanisms according to bladder and sphincter functions. CONCLUSIONS: There was a substantial overlap of bladder and sphincteric behaviors between patients with different levels of spinal injuries, but the trauma mechanism was not important to determine the bladder and sphincteric functions.

UNLABELLED: Biopsy is the gold standard for the diagnosis of conditions affecting the function of renal allografts. Obtaining representative tissue in biopsies is critical but these procedures are associated with up to 9% of complications and 20% of inadequate material. Although ultrasound guidance allows perfect control of depth and location of the graft, there is controversy regarding the cost-benefit of its use and reports of unsuitable material in ultrasound-guided biopsies are still high. PURPOSE: To compare ultrasound with the palpation method to guide biopsies in order to see if there is any difference between both methods and which one is better. PATIENTS AND METHODS: The casuistic consisted of 82 renal transplant patients (32 female and 50 male patients, age ranging between 5 and 64 yr; m=31.2 yr) randomized into two groups: GI, palpation-guided; GII, ultrasound-guided. Fifty-six biopsies were performed in GI and 66 in GII. RESULTS: Number of glomeruli, arcuate, and interlobar arteries and arterioles were compared in the two groups and were 503 (m=10) vs. 801 (m=12.9), 24 (m=0.5) vs. 38 (m=0.6), 104 (m=2.1) vs. 154 (m=2.5), and 174 (m=3.5) vs. 264 (4.3), respectively (p<0.05). Inadequate material for analysis in GI and GII was 7.1 and 7.6%, respectively (p=0.72). CONCLUSIONS: Although ultrasound guidance improves the number of glomeruli, arcuate, and interlobar arteries, as well as arterioles, compared with palpation-guided biopsies, there is no difference in the rate of adequate material between the two methods.

CONTEXT: There is still controversy as to the use and dosage of antimicrobial prophylaxis of the urinary infection associated with urethral catheterization in the post renal transplant period. OBJECTIVE: To determine whether patients develop urinary infection during short-term urethral catheterization after renal transplant without routine antimicrobial prophylaxis. DESIGN: Prospective study. SETTING: Kidney Transplantation Unit. SAMPLE: 20 patients submitted to non-complicated kidney transplant, with a normal urinary tract and no risk factors present regarding urinary infection. Aged 15 to 65 years. MAIN MEASUREMENTS: Before the transplant, material from the urethral meatus and urine were collected for culture. After the transplant, in the period during which the patient was with short-term urethral catheterization (4 to 5 days), material from the urethral meatus and urine from the bladder and the collecting bag were taken daily from all recipients for culture. RESULTS: There was a predominance of coagulase-negative Staphylococcus and S. viridans in the normal urethral meatus flora and in the first two days of urethral catheterization. After the second day, there was a predominance of E. coli and E. faecalis. Urinary infection did not occur during the period of urethral catheterization. In the follow up only one female patient (7%) had asymptomatic bacteriuria caused by E.coli after the withdrawal of the urethral catheter. CONCLUSIONS: Infection urinary does not occur during the period of urethral catheterization in kidney post-transplant patients. Thus, antimicrobial prophylaxis is not recommended for these patients to prevent urinary infection.

Thirty men having Parkinsons disease (PD) and 30 controls were studied prospectively by the use of the International Index of Erectile Function (IIEF) to assess erectile dysfunction (ED). Of the patients with PD (mean age of 59 years), 46.66% referred to the practice of sexual activity. All of the parkinsonians were using antiparkinsonian medication. In the control group (mean age of 63 years), 76.66% referred to the practice of sexual activity, 46.60% to arterial hypertension and 6.66% to diabetes mellitus. The median score for the PD group according to the IIEF was 34, and that for the controls 50. The main differences between the two groups were in the erectile function, orgasmic function and satisfaction with the sexual relationship. The IIEF is a multidimensional scale widely accepted to assess the ED. The data obtained suggest that ED is more frequent among parkinsonians and points out to the role of DP in the genesis of ED.

PURPOSE: We evaluate the incidence of incisional hernia after kidney transplantation, predisposing factors and the results of surgical repair with polypropylene mesh. MATERIALS AND METHODS: We reviewed the records of 371 consecutive kidney transplants performed between April 1995 and February 2000. Patients with clinical signs of hernia at the transplant incision site were included in the study. Predisposing factors for incisional hernia were also reviewed. A prospective protocol of surgical correction was established using polypropylene mesh and patient outcome was studied. RESULTS: We identified 14 patients (3.8%) with an incisional hernia at the transplant incision site. Hernias developed 3 to 840 days after transplant surgery and were significantly more common in white (p = 0.019) and cadaveric graft (p = 0.02) recipients. Predisposing factors in 11 cases included complications of transplant surgery in 7, bladder obstruction in 2, large polycystic kidneys in 1 and chronic pulmonary disease in 1. Surgical repair was performed by primary fascial approximation and polypropylene mesh reinforcement in 13 cases and by pre-peritoneal mesh placement in 1. Minor subcutaneous wound infection developed in 1 patient. No relapses were noted at a mean followup of 17.8 months. CONCLUSIONS: In the majority of cases incisional hernia develops in the first 3 months after transplant surgery. The incidence is significantly higher in white patients and after cadaveric donor transplantation. Surgical complications of transplant surgery are important predisposing factors for incisional hernia after kidney transplantation. Surgical repair using polypropylene mesh is safe and effective in this group of patients.

Chronic transplant nephropathy (CTN) is the most important cause of kidney graft dysfunction. Studies in adult populations have reported a beneficial effect of non-nephrotoxic mycophenolate mofetil (MMF) on graft function in this setting. However, few studies were reported in children in this setting. We therefore reviewed the charts/medical records of renal transplanted patients < 18 yr of age at a single center who had switched from azathioprine to MMF as a result of progressive loss in graft function, for which vascular, infectious, and urological causes were excluded. Serum creatinine (SCr) and calculated creatinine clearance were compared prior to and after MMF introduction. Thirteen patients (nine male/four female), followed-up for 59.3 +/- 35.4 months after transplantation, were analyzed. Age at MMF introduction was 14.2 +/- 3.6 yr. In 11 patients a previous biopsy had shown features of CTN and four patients also presented signs of chronic cyclosporin A (CsA) nephrotoxicity. MMF was started at a dose of 1211 +/- 351 mg/day, and the CsA dose was decreased from 6.69 +/- 3.15 mg/kg/day 6 months before MMF to 4.8 +/- 2.3 mg/kg/day at the time of MMF introduction. CsA was withdrawn in four patients. The median (25-75%) SCr value increased from 1.60 mg/dL (range 1.3 to 1.87 mg/dL) 6 months before MMF to 2.2 mg/dL (range 1.87-2.32 mg/dL) when MMF was introduced. Six months after introduction of MMF, the SCr level had decreased to 1.5 mg/dL (range 1.2-1.8 mg/dL) and remained stable until the last follow-up (17.5 +/- 9.2 months after MMF was started). A similar pattern occured with calculated SCr clearance. There were no acute rejections after changes in immunosuppression. The safety of MMF was also analyzed and in only one patient was the drug stopped as a result of intractable diarrhea. These findings suggest that MMF is sufficiently powerful to allow a decrease/withdrawal of CsA without the burden of acute rejection in a pediatric population with CTN.

The employment of synthetic mesh for incisional hernia repair in kidney-transplanted patients is rarely reported in the present literature. Many authors believe that mesh employment in such conditions is not safe due to fear of mesh related complications. From 1965 through 1999, a total of 1685 kidney transplants were performed at our Kidney Transplant Unit and 19 patients developed eventrations in the kidney transplant incision, an incidence of 1.1%. From September 1996 eight of these patients had prosthetic repair of the abdominal wall with onlay polypropylene mesh. All patients were under immunosuppressive therapy with prednisone, ciclosporine and azathioprine. Mean age was 48.8 years, mean body mass index was 22.5 and mean number of previous abdominal operations was 2.5. A large polypropylene mesh (Marlex mesh) was fixed over the aponeurosis after primary closure of the aponeurotic borders, as an onlay graft. There was neither morbidity nor mortality associated to the surgical procedure. No recurrences or long-term complications associated with mesh employment were verified after a follow-up ranging from one year to three years. We concluded that prosthetic repair of incisional hernia in transplanted patients can be performed routinely.

CONTEXT: Extension of pheochromocytomas to the inferior vena cava is rare. Multicentric tumors are rare as well, being present in up to 10% of cases. Surgery is the treatment of choice because of the long-term survival free of disease. DESIGN: Case report. CASE REPORT: We report on a case of right adrenal pheochromocytoma with extension to the supra-diaphragmatic vena cava, which underwent surgical excision through thoracophrenic laparotomy without the need for cardiopulmonary bypass. In a 6-year follow-up, another pheochromocytoma was found in the infra-renal Zuckerkandl's organ. Complete surgical excision of the tumor was performed by a median laparotomy and complete retroperitoneal dissection. In both cases, the total removal of the pheochromocytoma has been guaranteed by having margins free of tumor and a normal post-operative level of catecholamines. The pathological study revealed a malignant pheochromocytoma with margins free of neoplasia in both specimens.

Laparoscopy has gained acceptance as the ideal method of surgical treatment of the internal [figure: see text] genital organs in patients with intersex disorders. The intersexual states for which laparoscopy is needed are female and male pseudohermaphroditism, true hermaphroditism, and Turner's syndrome. In these patients, the indications for laparoscopy are the removal of normal gonads and ductal structures that are contrary to the assigned gender and the removal of dysgenetic gonads that are nonfunctional and that present potential for malignancy. In addition to being a minimally invasive surgery, one of the main advantages of this method is the lack of scars, a fact much appreciated by patients and their parents. Generally, gonadectomy is a straightforward operation because the gonads present with an accessible pedicle. Laparoscopic orchidopexy has been standardized and can be performed in patients in whom the testis must be relocated to the scrotum. The removal of ductal structures is also easily performed in most cases, whereas hysterectomy with resection of the vagina may present some difficulties owing to the location of these structures. In patients with a long vaginal component of the urogenital sinus, the distal segment must be removed by a retrograde perineal access, usually performed simultaneously with genitoplasty. Endocrinologists must be aware of the application of this method of treatment in intersex patients, and urologists proficient in laparoscopic techniques must extend their field of work in this area.
