[Urologic complications in renal transplantation. Study of 250 cases].

OBJECTIVE: The aim of this study is value the incidence of urological complications (fistulae and estenosis) in our serie of renal transplant, to analyze the variables that can influence in their appearance and the treatments used. Likewise, to value the follow-up of theses patients and the survival of the renal graft and of the patient. MATERIAL AND METHODS: 250 renal transplants are carried out between july of 1985 and october of 1998. The relationship among the variables you makes by means of the test chi 2 of Pearson and the test of Fisher; the contrasts of stockings with the t of Student; the survival of the organ and of the patient, by means of the analysis of curved of survival according to the method of Kaplan and Meier; and the comparison among curved of survival was carried out with the test of Cloth and Cox. RESULTS: Of the 250 transplants, 46 patients suffered for complications, 29 urinary fistulae (11.6%) and 21 estenosis (8.4%). The most frequent localization in both complications was the union uretero-vesical. The presence of urinary fistulae didn't influence negatively in a significant way nor over the survival of the implant (p < 0.211), neither over the patient's survival. The estenosis appearance was related in a significant way with the donor's age (p < 0.02). The estenosis presence was not related in a significant way neither with the survival of the implant neither with that of the receiver. CONCLUSIONS: The incidence of urological complications was of 18.4% (11.6% estenosis and 8.4% fistulae). The most frequent localization was the union uretero-vesical. The presence of estenosis correlated with the increase of the age of the donors. The technique of reimplante ureteral didn't influence in the results in a significant way. We don't find any relationship between the appearance of urological complications and the patient's survival.

[Bladder compression by collateral veins].

Many space-filling injuries (e.g. haematoma, abscess, aneurysm, lymphocele, neoplasia etc.) may result in extrinsic compression of the bladder. We contribute one case report of compression of the bladder from collateral venous circulation in a patient who came for a left varicocele.

[Squamous carcinoma of the penis].

OBJECTIVE: To present our experience with squamous cell carcinoma of the penis. METHODS: We reviewed our series of 73 squamous cell carcinoma of the penis over the last 23 years. Patient mean age was 65.7 years. All lesions had been previously biopsied. Patient records were reviewed for a history of phimosis and related lesions. The histological, clinical and therapeutic aspects, and survival are analyzed. RESULTS: Most of the squamous cell carcinoma of the penis were superficial lesions (pT1). Treatment was by partial penile resection in 42 cases, total penile resection in 9, and emasculation in 2 cases. Conservative surgery was performed in 20 cases (tumor excision in 14 and posthectomy in 6 cases). Lymphadenectomy was performed in 11 patients. Eight patients received radiotherapy to the inguinal region. The rate of recurrence after surgery was 11% (8 cases). Five of the 8 patients with tumor recurrence had been treated by conservative surgery. The 5-year survival rate was 78%. CONCLUSIONS: Penile cancer is uncommon and accounts for less than 1% of tumors in the male in our setting. A higher incidence has been found in men with phimosis, poor hygiene and low sociocultural level. Partial penile resection is the treatment of choice for the primary lesion. The outcome is worse in patients with invasive tumor, poor cell differentiation, ulceroendophytic morphology, and above all in patients with metastatic adenopathy. Radiotherapy provided no benefits, made inguinal evaluation difficult and increased the morbidity in some cases. Patients with pT1 tumor and good cell differentiation showed no metastatic adenopathy during follow-up. Patient follow-up is fundamental to detect recurrence or metastatic adenopathy and to institute treatment immediately.

[Invasive angiomyxoma of the scrotum].

Herein we report on a 70-year-old patient with invasive angiomyxoma of the scrotum that had evolved for more than 30 years. The tumor's enormous size (4.225 gms.), its rarity and clinical behaviour are highlighted. There was no distant metastasis and tumor recurrence was by local infiltration. Its histologic features, which are like those of myxomatous tumors, are described.

[Diagnostic and therapeutic value of puncture nephrostomy. Review of 45 cases].

The present study reports our experience in 45 patients submitted to percutaneous nephrostomy. We describe the indications of this procedure and highlight its efficacy in making etiologic diagnosis and recovering renal function. Similarly, we underscore its efficacy in the treatment of sepsis, anuria, and dissolution of uric acid calculi. The low incidence rate of complications and no mortality from this procedure, and its diagnostic and therapeutic efficacy make it a common procedure in day-to-day urological practice.

[Puncture of urinary tract for the diagnosis of its obstruction. Review of 60 cases].

We present the results of percutaneous translumbar puncture (PTP) performed in 60 patients diagnosed as having urinary tract obstruction in whom the urographic, ultrasonographic, arteriographic work up and placement of a ureteral catheter for ascending pyelography failed to determine the exact level or nature of the obstruction. We emphasize the fact that PTP revealed the site of obstruction or showed the urinary tract was normal in 86.6% of the cases. The level of obstruction was undetermined in 8.3%, and in 5% of the cases PTP could not be performed. In 75% of the cases, the diagnosis of the nature of the obstruction yielded by PTP was confirmed medically or surgically. This was unconfirmed in 11.6%. Minor complications, most of which were due to extravasation of the contrast medium, were observed in only 18.3%.
