[Recurrent nonparasitic chyluria].

OBJECTIVE: To describe a case of recurrent chyluria and review the diagnostic and therapeutic methods. METHODS/RESULTS: A case of non parasitic recurrent chyluria is presented. Retrograde pyelography demonstrated pyelolymphatic reflux. The patient presented chemical pyelitis secondary to the contrast medium which caused remission of the condition. CONCLUSIONS: Chyluria is uncommon in our setting. Postprandial cystoscopy permits identification of the compromised renoureteral unit and perform pyelic instillation of sclerosing agents. Surgery should be reserved for those cases in whom conservative management has failed.

[Urethroplasty with lyophilized human dura mater].

OBJECTIVE: This article reports our experience with lyophilized human dura in the treatment of complex urethral stenosis. METHOD: Seven patients with iatrogenic/inflammatory urethral stricture underwent a 13 cms long x 1.5 cms wide medial urethral augmentation. RESULTS: During a mean follow-up of 23 months, good results accounted for 85.7%. CONCLUSION: Lyophilized dura patches constitute a suitable choice in selected patients who, for local or systemic reasons, are not good candidates for other urethroplasty procedures.

[Cefminox versus cefotaxime in the treatment of complicated urinary tract infection].

A comparative study of Cefminox, a new cefamicin, and Cefotaxime was conducted to evaluate the efficacy and safety of the former in the treatment of complicated urinary infection, and to correlate in both cases the bacteriological response with isolates MICs. To this end a phase III, randomized, blind and controlled clinical trial was conducted in 22 patients who met the study's preestablished criteria, 19 of which were evaluable. Both treatments achieved 100% clinical efficacy, while microbiological eradication was accomplished in 90.9% patients treated with Cefminox and 75% patients who received the comparator. Cefminox shows greater in vivo activity than that expected for the MICs, excellent efficacy and safety.

[Multilocular cystic renal adenocarcinoma].

On detecting a complex cystic renal mass, we are faced with the problem of making the differential diagnosis from a variety of diseases, some of very distinct nature and prognosis. Surgical exploration may occasionally be warranted to make the diagnosis since no radiological or analytical method, including cytological analysis of its content, is absolutely reliable. A 46-year-old male patient with multicystic renal adenocarcinoma is described. We discuss the diagnostic and therapeutic dilemmas that arise on detecting a multilocular renal mass in an adult patient.

[Controversies over regional lymphadenectomy in carcinoma of the penis].

Epidermoid carcinoma of the penis, although rare, is a very aggressive tumor type. The presence or absence of inguinal metastasis is an essential prognostic factor. Treatment of these metastases is one of the current controversies in urological practice; i.e., when and to what extent lymphadenectomy should be performed. Of 24 patients with penile carcinoma, 10 had undergone regional lymphadenectomy over the past 8 years at our institution. Following treatment of the primary penile tumor, 6 patients had palpable inguinal nodes that persisted after treatment with antibiotic and antiinflammatory agents for 6 weeks. Of these, 3 had a positive node biopsy. They were submitted to regional lymphadenectomy which revealed node metastasis in 5 cases (2 pN3, 2 pN2 and 1 pN1). The patients with no palpable nodes were closely followed and were submitted to lymphadenectomy when these appeared (3 cases). The fatal outcome of 2 cases (both pN3) prompted us to perform lymphadenectomy prophylactically in the last case, a 40-year-old male with pT2G2 N0 penile cancer. This approach is advocated in patients under 65 with invasive penile carcinoma (pT greater than 1) or a high histological grade of malignancy (G2 and G3).

[Incidence of different types of hypercalciuria in the Madrid area. Demographic features].

A study to determine the incidence of idiopathic hypercalciuria was performed in 110 patients (59 females, 51 males). Classification of this metabolic disorder according to its different types revealed the following incidence: 50% for absorptive hypercalciuria, 14.5% for hypercalciuria from loss of renal phosphates, and 30% for renal hypercalciuria. Insufficient biochemical data with a significant value did not permit classification of 6.3%. Analysis of distribution according to sex revealed a similar incidence (50%) for males and females for absorptive hypercalciuria, a prevalence in men (71%) for hypercalciuria due to loss of renal phosphates, and a prevalence in females (64.7%) for renal hypercalciuria. However, correction of these data according to the male to female ratio of our study population revealed renal hypercalciuria to be more prevalent in females whereas absorptive hypercalciuria and hypercalciuria from loss of renal phosphates were more prevalent in men. Analysis of distribution according to age revealed a direct relationship between the increased incidence of renal hypercalciuria and patient age.

[Endo-urologic treatment of the uretero-intestinal stenoses in patients subjected to diversion].

Surgical repair of uretero-enteric strictures in patients with enteric conduit urinary diversion (incidence rate 4-8%) is difficult and has a high morbidity. With the development of endo-urologic techniques and ureteral catheters, long-term insertion of stents in the treatment of strictures has become possible and safe. We have performed long-term uretero-enteric stenting with 7-8 Fr double-J catheters in 5 patients with 6 strictures: 3 ureteroileal and 3 uretero-colic. In three cases (2 colonic conduits, 1 ileal conduit) the stent was inserted anterogradely following intercostal renal percutaneous punctures and dilatation of the stricture with teflon dilators (1 case), balloon catheter (1 case), or following the incision of the stricture (1 case). In one patient with a double uretero-enteric stricture of the ileal conduit, guide-wires were successfully inserted retrogradely which permitted subsequent high pressure dilatation of the uretero-ileal strictures with a 15 Fr balloon catheter. We used the same approach in another patient with a right uretero-colic stricture. The catheters were left indwelling for 7 to 35 months and were changed every 3 months with no remarkable observations other than 3 episodes of fever which quickly resolved with antibiotic treatment. Although is has been reported that uretero-enteric strictures are particularly refractory to endo-urologic treatment and a significant morbidity rate has been associated with long-term ureteral stenting, our results show that the approach was well-tolerated by all of the patients.

[Non-functioning renal graft: indications for transplant excision].

Of 107 renal transplants, 25 patients who were restarted on dialysis due to graft failure were studied. Of these, 20 underwent renal transplant nephrectomy. Graft failure was due to a progressive functional loss in 18 (16.8%) and 4 other grafts were non-functioning from the outset. Of these 22 cases, 17 (77.2%) underwent transplant removal. Three (15%) viable grafts were removed, 2 due to urologic complications and 1 due to hemorrhage following percutaneous renal biopsy. A non-functioning renal graft was left in situ in 5 patients. Rejection was the most frequent cause of transplant nephrectomy (45%), followed by arterial thrombosis (25%) and infection (15%). Eighty-five percent of these procedures were performed before one year post-transplantation, usually 1-4 weeks after diagnosis. Only 3 (13.6%) of the 22 non-functioning grafts removed were viable for more than 12 months after transplantation. The surgical technique was subcapsular in 60% and classical in the remaining cases. This was the surgical approach in all emergency cases. Except for one postoperative death directly related with surgery, complications were observed in 10% of the cases. These did not present as being especially uncommonly severe. The estimated 10-year posttransplantation survival rates for patients and grafts were 87.4% and 62.9%, respectively. The clinical evidence for transplant nephrectomy correlated well with the histologic evidence from the surgical specimens relative to the diagnosis of acute rejection and vascular thrombosis, despite its clinical under-utilization, and were discordant for urinary fistula, chronic rejection and sepsis.(ABSTRACT TRUNCATED AT 250 WORDS)

[Value of ultrasound in the diagnosis of acute rejection of a kidney transplant].

To determine the usefulness of ultrasound in the diagnosis of acute renal graft failure, 48 renal transplants were retrospectively studied. The characteristic morphologic signs of acute rejection (AR) were compared with the histologic analysis of the graft using material obtained from percutaneous renal biopsy and/or transplantectomy. From the ultrasound scanning performed at the time the histologic specimens were taken, the following four easily identifiable signs were used for the assessment: 1) increased size, 2) increased volume and echo negativity of pyramids, 3) sinus compression, and 4) patchy cortex/sinus destructuring. Correlation of each sign with the anatomopathological data revealed a high sensitivity and predictive value but low specificity for ultrasound in the diagnosis of AR. Its true predictive value will depend on the demonstration of various signs simultaneously, with the advantage that, unlike other techniques, it is noninvasive and can be performed serially.
