Kidney transplantation in children with bladder augmentation or ileal conduit diversion.

INTRODUCTION: Various congenital and acquired diseases of the lower urinary tract can lead to chronic renal failure requiring renal replacement therapy. AIM: The aim of the study was to assess problems and results of kidney transplantation in children with significant lower urinary tract dysfunction. MATERIALS AND METHODS: Between 1984 and 2007, there were 33 kidney transplantations in children with end-stage renal disease and severe lower tract dysfunction out of 539 kidney transplantations performed in our department. The patients were 23 males and 10 females. Thirty patients received a kidney from a deceased donor, the remaining 3 from a living related donor. The age at transplantation ranged from 2.25 years to 19 years. In 26 patients an ileal conduit modo Bricker was created (in 21 patients at transplant operation). Bladder augmentation was performed in 6 patients and a continent urinary reservoir was created in 1. RESULTS: Post-transplant follow-up ranged from 7 to 88 months (mean 32 months). Overall patient survival is 100% and graft survival is 97%. Creatinine concentrations ranged from 0.3 to 3.4 mg% (mean 0.92 mg%). Surgical complications were diagnosed in 16 patients. All surgical complications were treated successfully and none of them caused graft loss. Urinary tract infections (UTI) were the most commonly observed complication, occurring in 26/33 (78%) patients, but the majority of these UTI were asymptomatic and had no influence on graft function. CONCLUSIONS: Kidney transplantation in children with lower urinary tract dysfunction and end-stage renal failure offers excellent medium term results in our experience, despite the creation of non-standard urinary drainage. Recurrent urinary tract infections are the most common complications in these patients, but in the majority of cases this does not lead to impairment of graft function.

Treatment of neuropathic urinary and faecal incontinence.

The author presents 14 children after meningomyelocoele repair with faecal and urinary incontinence, aged from 6 to 17 years who have undergone the MACE procedure. MACE with synchronous Mitrofanoff continent stoma creation was performed in one child with severe stenosis of the urethra. MACE with simultaneous bladder augmentation was used in 10 patients. 5 of them underwent colocystoplasty, 3 had ileocystoplasty and 2 ureterocystoplasty. Of these 10 children, three have additionally undergone the Mitrofanoff procedure. Patients' follow-up ranged from six months to two years. Three children had trouble with the MACE stoma because of its stenosis. One of them required revision of the stoma. All patients became clean and dry, and this operation improved not only their quality of life, but also their independence.

Complete duplication of the bladder, urethra, vagina, and uterus in girls.

UNLABELLED: OBJECTIVES. To present our experience with 3 girls with complete duplication of the bladder, urethra, vagina, and uterus, a very rare anomaly, and review published reports. Associated anomalies in these cases represent a wide spectrum. METHODS: We report 3 girls with complete duplication of the bladder, urethra, vagina, and uterus. The associated anomalies were different in each child. The first patient had a symphysis diastasis creating an abdominal hernia with two bladders dislocated into this space. The second patient had anal atresia with colon duplication. The third had cloacal exstrophy with one opened bladder and a second closed, with persistent urogenital sinus. Each patient was carefully evaluated, but the anatomy in 2 patients was not completely defined until surgical exploration. RESULTS: Each girl underwent surgical repair. In the first patient, iliac osteotomy, approximation of the symphysis pubis, and excision of the hernia was done. In the second, excision of the common wall between the two descending colons and posterior sagittal anorectoplasty were performed. In the third patient, staged reconstruction of the cloacal exstrophy with anastomosis of the bladders and vaginas was done. CONCLUSIONS: Complete duplication of the urogenital system in girls is associated with different anomalies. Which surgical procedures will be required depends on the multiple anatomic variables.

The authors report 3 girls with complete duplication of the bladder, urethra, vagina and uterus. Defect's anatomy and associated anomalies are described. In support of the literature therapeutic procedure is discussed, which must be individualized in each case.

Trisomy 3q11-q29 is recurrently observed in B-cell non-Hodgkin's lymphomas associated with cold agglutinin syndrome.

Three cases of low-grade B-cell non-Hodgkin's lymphoma associated with cold agglutinin syndrome, cytogenetically characterized by partial trisomy 3, are presented in this report. Our data suggest that the long arm of chromosome 3 might be of particular importance in the pathogenesis of this subgroup of lymphomas.

Bladder autoaugmentation in myelodysplastic children.

OBJECTIVE: To present the long-term results of bladder autoaugmentation in myelodysplastic children with low compliance neurogenic bladders who failed attempts at medical management, including clean intermittent catheterization (CIC) and pharmacological bladder relaxation. PATIENTS AND METHODS: Twenty-one patients with a neurogenic bladder after myelomeningocele operations (mean age 9.5 years, range 3-16) underwent autoaugmentation; 12 children were paraplegic and hydrocephalic, and were treated by insertion of a ventriculoperitoneal valve. All patients had low-compliance neurogenic bladders confirmed urodynamically. Ten patients had vesico-ureteric reflux (VUR) and eight had dilated upper urinary tracts with no reflux. All patients had been treated pre-operatively using CIC and anticholinergic agents, with no success. RESULTS: Of 21 children treated surgically, 17 were assessed urodynamically and examined to determine the condition of the upper and lower urinary tract. The follow-up ranged from 3 months to 8 years (mean 6 years). In 13 patients the bladder capacity increased by approximately 60 mL and in 14 the intravesical pressure decreased by approximately 65 cmH2O. Fourteen children were continent using CIC (from 3- to 4-hourly); in the six patients with VUR the reflux resolved in two, decreased in two and remained unchanged in two. Of eight patients with dilated upper tracts but no reflux, seven improved. There was no improvement in bladder capacity in four patients and no reduction in intravesical pressure in three. Two patients underwent enterocystoplasty (one ileocystoplasty and one colocystoplasty) with good results. Two children needed anticholinergic agents after autoaugmentation. CONCLUSIONS: Autoaugmentation effectively reduces high intravesical pressure and provides a sufficient increase in bladder capacity with a concomitant improvement in urodynamic values. The present method allows the extent of the surgical procedure to be limited to the extraperitoneal space and thus maintains all of other options. Bladder autoaugmentation is a reasonable alternative to enterocystoplasty in selected patients.
