1/489. Reconstruction ('undiversion') of the diverted urinary tract.

    Two operations to permit urinary drainage had been performed in a 2 1/2-year-old boy born with obstructing urethral valves, but infections and other compications were a constant threat, especially since the child had only one functioning kidney. After the anomalous valves were ablated endoscopically, the urinary tract was reconstructed, as shown here, to "undivert" the previously fashioned ileal loop bypass.

2/489. Transient pseudo-hypoaldosteronism following resection of the ileum: normal level of lymphocytic aldosterone receptors outside the acute phase.

    Pseudo-hypoaldosteronism (PHA) is due to mineralocorticoid resistance and manifests as hyponatremia and hyperkalemia with increased plasma aldosterone levels. It may be familial or secondary to abnormal renal sodium handling. We report the case of a 54-year-old woman with multifocal cancer of the colon, who developed PHA after subtotal colectomy, ileal resection and jejunostomy. She was treated with 6 g of salt daily to prevent dehydration, which she stopped herself because of reduced fecal losses. One month later she was admitted with signs of acute adrenal failure, i.e. fatigue, severe nausea, blood pressure of 80/60 mmHg, extracellular dehydration, hyponatremia (118 mmol/l); hyperkalemia (7.6 mmol/l), increased blood urea nitrogen (BUN) (200 mg/dl) and creatininemia (2.5 mg/dl), and decreased plasma bicarbonates level (HCO3-: 16 mmol/l; N: 27-30). However, the plasma cortisol was high (66 microg/100 ml at 10:00 h; N: 8-15) and the ACTH was normal (13 pg/ml, N: 10-60); there was a marked increase in plasma renin activity (>37 ng/ml/h; N supine <3), active renin (869 pg/ml; N supine: 1.120), aldosterone (>2000 pg/ml; N supine <150) and plasma AVP (20 pmol/l; N: 0.5-2.5). The plasma ANH level was 38 pmol/l (N supine: 5-25). A urinary steroidogram resulted in highly elevated tetrahydrocortisol (THF: 13.3 mg/24h; N: 1.4 /-0.8) with no increase in tetrahydrocortisone (THE: 3.16 mg/24h; N: 2.7 /-2.0) excretion, and with low THE/THF (0.24; N: 1.87 /-0.36) and alpha THF/THF (0.35; N: 0.92 /-0.42) ratios. The number of mineralocorticoid receptors in mononuclear leukocytes was in the lower normal range for age, while the number of glucocorticoid receptors was reduced. Small-bowel resection in ileostomized patients causes excessive fecal sodium losses and results in chronic sodium depletion with contraction of the plasma volume and severe secondary hyperaldosteronism. Nevertheless, this hyperaldosteronism may be associated with hyponatremia and hyperkalemia suggesting PHA related to the major importance of the colon for the absorption of sodium. In conclusion, this case report emphasizes 1) the possibility of a syndrome of acquired PHA with severe hyperkalemia after resection of the ileum and colon responding to oral salt supplementation; 2) the major increase in AVP and the small increase in ANH; 3) the strong increase in urinary THF with low THE/THF and alpha THF/THF ratios; 4) the normal number of lymphocytic mineralocorticoid receptors outside the acute episode.

3/489. Management of prostatic fistulas.

    Prostatic fistulas communicating with the rectum or perineal skin are unusual complications of a prostatic operation, pelvic trauma, prostatic abscess or other iatrogenic injury. A third of these fistulas may close spontaneously with proper urinary drainage and avoidance of fecal soilage. The many operative procedures described for the repair of these fistulas indicate that no ideal method of repair can be applied to every case. Operative management should be mandated by the size, location and duration of the fistula as well as by the surgeon's experience with the various anatomic approaches.

4/489. Disseminated herpes simplex virus infection in a renal transplant patient as possible cause of repeated urinary extravasations.

    Disseminated herpes simplex virus type 2 (HSV-2) infections are infrequent in patients receiving organ transplants, but usually have a poor outcome. We describe the case of a renal transplant patient who developed a disseminated HSV-2 infection with repeated urinary extravasations. The diagnosis was carried out using a multiplex polymerase chain reaction nested assay and it suggested HSV-2 as a possible cause of repeated urinary fistulas.

5/489. Striae and acne following cardiac surgery in a child.

    We report a 13-year-old girl with extensive striae and an acneiform eruption following surgery for complex congenital heart disease. These findings were associated with elevated serum and urinary cortisol levels with loss of diurnal rhythm. The resolution of the eruption and the fading of her striae coincided in time with normalization of her blood parameters on day 72 postoperatively. We conclude that the cause of steroid excess in our patient was stress induced by the cardiac surgery and a complicated and protracted postoperative course. To our knowledge, this is the first report in the English language literature of skin changes due to endogenous hypercortisolaemia caused by intense physical and emotional stress.

7/489. holmium: YAG laser endoureterotomy in the treatment of ureteroenteric strictures following orthotopic urinary diversion.

    The management of ureteroenteric strictures in patients who have undergone urinary diversion can be challenging. In those patients with an orthotopic neobladder, anastomotic ureteral strictures can be treated endoscopically using a retrograde or antegrade approach. The availability of small (7.5F) flexible ureteroscopes, as well as the use of the holmium laser has facilitated the ability to precisely incise the stricture under direct endoscopic visualization (endoureterotomy). We describe our technique for laser endoureterotomy in patients with ureteroenteric strictures following orthotopic urinary diversion.

8/489. Symptomatic cervical macrocyst as a late complication of subtotal hysterectomy. A case report.

    BACKGROUND: Ablation of the endocervical canal is sometimes performed as an adjunct to subtotal hysterectomy in an attempt to reduce mucous discharge and the risk of future neoplasia. Cystic accumulations within the canal of a partially obliterated cervical stump have not previously been reported to follow this practice. CASE REPORT: A 41-year-old woman presented with subacute cramping and cystic enlargement of the cervical stump on clinical, sonographic and magnetic resonance evaluation four years subsequent to a subtotal hysterectomy performed for menorrhagia. Cervical biopsies and cytology were benign, and vaginal trachelectomy was performed. pathology demonstrated the fluid pocket to be a very large retention cyst (nabothian) that had occupied and distended the partially obliterated endocervical canal. CONCLUSION: Ablation of the cervical canal at subtotal hysterectomy may result in symptomatic entrapment of nabothian cysts. Internalization of the transformation zone and partial obliteration of the canal are postulated as predisposing factors.

9/489. A stormy transplant case with happy ending.

    A 12-year-old female patient with end-stage renal failure whose primary disease was reflux nephropathy, was first admitted for augmentation cystoplasty by using an ileum segment because of contracted urinary bladder. Four months later, she had a renal transplantation from her father on March 28th 1997. The first three days after the operation were uneventful. On the fourth day, she presented a severe rejection episode and was treated with steroid and ATG. A urinary fistula developed and she underwent surgery again on the 14th postoperative day. At surgery, apical resection omentoplasty nephrostomy DJ replacement were performed. The postoperative period after the second operation was full of problems for both the patient and the transplantation team. She was discharged from hospital on the 40th postoperative day with excellent renal function (a serum creatinine level of 1 mg/dl) and with full recovery.

10/489. Sacrococcygeal teratoma: a series of 19 cases with long-term follow-up.

    A series of 19 cases of sacrococcygeal teratoma (SCT) with follow-up of 5 to 25 years is presented. Twelve patients were neonates, age 0 to 26 days (5 immature teratomas and 7 mature teratomas, representing 3, 6, 2, and 1 Altman's type I, II, III, and IV tumors, respectively), four were infants, age 1 to 6 months (all mature teratomas, representing 1, 1, and 2 Altman's type I, II, and IV tumors), and 3 were children, age 1 to 4 years (all malignant teratomas, all Altman's IV tumors). Eight babies were delivered by elective caesarean section (CS). Though the mean gestational age at CS was 34.3 weeks in our series, we now believe that CS often must be performed earlier, depending on a tumor size or fetal condition. Eleven neonates and 4 infants were operated upon using a sacral approach in 10 and an abdominosacral approach in 5, and all survived. However, 4 patients had neurogenic bladder and were treated by urinary catheterization or vesicostomy for 2 to 5 years after surgery. Postoperative urogenital sequelae are seen in patients with a large tumor, urethral compression, urinary retention, or edema of the lower body. Malignant tumors usually had metastasized by the time of diagnosis, but the prognosis for outcome has been improved following surgery and combination chemotherapy.
