Stomach versus sigmoid colon in children undergoing major reconstruction of the lower urinary tract

A review of 50 patients who underwent intestinocystoplasty (ICP) or gastrocystoplasty (GCP) replacement at our department during an 8-year period is presented. The most common diagnoses were neurogenic bladder and bladder exstrophy. A total of 48 patients underwent augmentation cystoplasty and 2 had total bladder replacement. Mean follow-up time was 42 months. The clinical and metabolic aspects of the two types of ICP are reported. Hyperchloremic acidosis requiring therapy was not encountered, although mild degrees were seen after sigmoid augmentation in 36% of patients. A dysuria-hematuria syndrome (DHS) was seen in 50% of the patients who underwent GCP. Operative mortality rate was nil. Significant surgical complications occurred in 36% of the patients. The overall success rate for ICP and GCP in this series was 79.15%. ICP gives effective results when used to increase the compliance of the lower urinary tract, but problems related to electrolyte absorption, stones, and mucus production are often encountered. In GCP electrolyte absorption is practically eliminated, so that this technique can be used in patients with renal damage. In addition, patients with a normal bladder plate (bladder exstrophy) can achieve normal voiding with time. The authors believe that patients must be made aware of the possibility of DHS and that this syndrome needs further investigation.     

Successful Embolization of Coronary Arteriovenous Fistula Using an Interlocking Detachable Coil

Although the efficacy and feasibility of coil embolization of coronary arteriovenous fistulas have been reported, the procedure may be complicated by migration of the coil into peripheral vessels or pulmonary arteries. We report two cases of successful coil embolization of such lesions using an interlocking detachable coil. This system can provide safer and more effective coil embolization in patients with coronary arteriovenous fistula.     

The use of magnetic resonance imaging in the assessment of malignant vaginal fistulas

The objective of this study was to determine whether magnetic resonance imaging (MRI) could reliably demonstrate fistulas and any associated mass and to see whether these findings were beneficial in the management of the fistula. Twelve consecutive patients presenting with suspected vaginal fistulas were examined prospectively with MRI, using a combination of sequences, for the presence, extent and configuration of fistulas and any associated mass. Comparison was made with CT when available. All patients underwent examination under anesthesia (EUA) and the findings compared. Of the 12 women presenting, seven had vesico-vaginal fistulas (VVF) and seven had recto-vaginal fistulas (RVF). Four women had both types of fistulas. The underlying pathology was cervical cancer (seven cases), colonic cancer (three cases), breast cancer (one case) and ovarian cancer (one case). Vaginal fistulas were unequivocally seen on MRI in eight of 10 cases with fistulas. In the two cases with a difference between the MRI and EUA findings, the MRI was interpreted as showing more than was found at EUA. In the seven women with VVF, MRI detected five of the cases. In the seven women with RVF, MRI detected all seven cases. Magnetic resonance imaging was correct in determining the presence of recurrent disease in the pelvis when an associated mass was seen (seven cases). Computer-assisted tomography was compared in 10 cases and in six cases, the results were comparable and in four cases, more information was obtained from the MRI. Magnetic resonance imaging appears to be accurate in detecting and defining complex gynecologic fistulas and should be considered the investigation of choice to aid the planning of restorative, salvage or palliative surgery.     

Does circumcision alter the periurethral bacterial flora?

A prospective study of 25 boys who underwent circumcision for medical reason was performed. Specimens of periurethral bacterial flora were taken before operation as well as 3 weeks after surgery, so that each boy acted as his own control. Before circumcision, 13 (52%) harboured uropathogenic organisms (Escherichia coli and other coliforms, Enterococcus spp, Proteus spp, Pseudomonas spp, and Klebsiella spp); after circumcision, none of the boys had uropathogens, the only organisms cultured from the periurethral region being skin commensals. We postulate that circumcision converts a ‘cul-de-sac' that is a reservoir of organisms capable of causing ascending urinary tract infection into a surface colonised by natural skin organisms. This study provides circumstantial evidence supporting the idea that circumcision in well-selected patients may confer protection from urine infection. Accepted: 15 March 1997     

Intramural leiomyoma of the bladder

Mesodermal tumors of the urinary bladder are rare and the majority of them are malignant. We report a case of an intramural leiomyoma of the bladder presenting with symptoms of a mild lower urinary tract infection. The patient was managed with partial cystectomy and the outcome was excellent. Received: 31 May 1999; Revised: 21 September 1999; Accepted: 21 September 1999

Endogenous urinary steroids in premenopausal women with uterine leiomyomas.

OBJECTIVES: To study the effect of endogenous steroids on the presence of uterine leiomyomas. METHODS: Urine samples of 27 premenopausal women with leiomyomas and 25 age-matched healthy premenopausal women were collected. The concentration of estrogens and androgens in the urine samples of the two groups were determined using a gas chromatography mass spectrometer and the two groups were compared. To study metabolic changes in patients indirectly, the concentration ratios of precursor metabolite to product metabolite of the two groups were also compared. RESULTS: Urinary concentrations of 17beta-estradiol, 5-androstene-3beta, 16beta, 17beta, triol, 11-keto-ethiocholanolone, 11beta-hydroxy-androsterone, 11beta-hydroxy-etiocholanolone, THS, THA, THE, alpha-cortol and beta-cortol were significantly higher in patients than in controls. The concentration ratios of 17beta-estradiol/estrone and 11/beta-hydroxy-ethiocholanolone/11beta-hydroxy-androsterone increased in patients. CONCLUSIONS: The presence of uterine leiomyomas correlates with an increase in urinary concentrations of estrogens and androgens, and it appears to be caused by a decrease in patients' metabolism of steroids.     

Tracheoesophageal fistula: New option in management

Tracheoesophageal fistula is a life threatening condition. Patients not managed surgically ultimately die of their disease. Surgical management is the treatment of choice. We present a case of a patient that developed a tracheoesophageal fistula after tracheostomy. Surgical repair was done which failed due to infection. The patient was managed with the help of an esophageal stent and Trichloroacetic Acid cautery. This approach can be used in selected patients, depending upon the size and site of TEE Larger fistulae and those situated lower down e.g. supra carinal cannot be managed by this technique.
