OBJECTIVE: To describe a case of solitary crossed renal ectopia that had been incidentally discovered in a healthy male with a previous history of spinal surgery. METHODS/RESULTS: A 43-year-old male who had undergone two surgical procedures for severe scoliosis of the thoracic spine when he was 7 years of age, consulted for symptoms of unspecific urethritis that had just remitted. Abdominal ultrasound and excretory urography revealed a solitary crossed ectopia on the right side and the spinal x-ray showed congenital fusion of the cervical vertebrae (Klippel-Feil syndrome). CONCLUSIONS: Crossed ectopia of a solitary kidney is an exceedingly rare anomaly of the urinary tract (about 30 cases have been reported) combining renal agenesia of one side, contralateral displacement of the ureter draining the only kidney and agenesia or hypoplasia of the other ureter. It is frequently an incidental finding, although it may be associated with congenital spinal anomalies and even severe genital and anal anomalies.
OBJECTIVE: To study the number of authors of papers published in Actas Urologicas Españolas, and to assess the consequences on multiple authorship of the restriction to 6 of the number of authors for paper, established in the instructions for authors since January 1995. METHODS: The authors and papers appearing on sections "Originals". "Reviews" and "Case reports" from 1992 to 1995, were counted. RESULTS: Five hundred and forty eight papers were reviewed. The mean (+/- standard deviation) number of authors (6.1 +/- 2; 95% IC = 5.9-6.3) didn't show a statistically significant change between the 4 studied years (ANOVA, F = 1.42; p = 0.23). Fifty percent of the Originals and Reviews and 36% of Case reports had more than 6 authors and these proportions didn't change significantly between years (chi 2 = 3.48; p = 0.32), even considering that more than one third of papers published in 1995 were accepted that year. CONCLUSIONS: A great number of authors should modify their habits of co-authorship on papers submitted to Actas Urologicas Españolas, in order to fulfill the new instructions for authors.

Scrotal ultrasound has been used to confirm the resolution of hydrocele testis after sclerosing with different solutions, and so, early recurrences with a multicystic appearance were occasionally observed. This finding was considered a complication of the sclerosant treatment needing a surgical option [1]. We have observed that a multilocular recurrence of hydrocele after percutaneous sclerosing with polidocanol is frequently followed by spontaneous cure.
A granuloma caused by a forgotten laparotomy gauze (gauzoma) was suspected in a patient with general symptoms, a well-defined pararenal mass on computed tomography and a history of retroperitoneal surgery, and was subsequently confirmed at surgery. The image diagnosis of retained surgical sponges is briefly reviewed.
OBJECTIVE: Drug-induced lithiasis was well-known some years ago, when sulfonamides poorly soluble in urine were in use. Now, they are again in use for some opportunistic AIDS-related infections. We report herein the case of an AIDS patient, treated with sulfadiazine because of Nocardia pneumonia, that came to the emergency room in acute renal failure. METHODS/RESULTS: Obstructive uropathy due to radiolucent calculi was suspected and retrograde ureteral catheterization was necessary. The calculi recovered were identified as N-acetyl sulfadiazine by infrared spectrophotometry. CONCLUSION: Rapid improvement can be achieved in these patients when the drug is discontinued or decrease and systemic fluid and urine alkalinization are started.

Between 1982 and 1993, 6 male and 14 female patients underwent partial or total nephrectomy due to renal angiomyolipoma (AML). Presentation forms were: in 6 cases (30%) acute pain with severe haematuria or signs of visceral bleeding, 3 (15%) acute pain without other symptoms, 7 (35%) chronic pain associated to haematuria or fever, or isolated haematuria, and in 4 (20%) it was a chance finding. No significant differences were found among tumor sizes considering the severity of the presentation form, but all AMLs with serious signs and symptoms had more than 5 cm diameter. A pre-operative diagnosis of AML was made in 15 (75%) patients, while 5 (25%) underwent surgery for other presumed diagnosis. Nine were conservative procedures of renal parenchyma and 11 were total or radical nephrectomies. There were no significant differences between tumour sizes by treatment performed. The authors review the imaging diagnostic difficulties and the various criteria supporting surgery in AML, and conclude by recommending individualized diagnosis and treatment in patients with AML suspicion of including puncture biopsy or cytology when in doubt, trying to avoid surgery in well characterized tumours, under 4 or 5 cm, provided that they could be followed-up regularly.
Twenty male patients aged 26-79 years old, with symptomatic unilateral hydrocele, were treated by evacuation puncture and intracavitary instillation of 2 ml of a 3% polydocanol solution. In 13 cases, treatment was done ambulatory and only in the first few cases sperm cord anaesthetics was used. Regular follow-up of at least 6 months was made. No complications were encountered and only one third of patients complained of mild pain. In 12 cases (60%) hydrocele cure was achieved and 6 relapsed (another 2 were lost to follow-up). Testes ultrasound performed 1 month later showed that 4 patients had non-symptomatic multicystic relapse, which disappeared spontaneously within 6 months in three cases. The advantages of this substance in hydrocele non-surgical treatment versus other therapies used until now are reviewed, concluding by recommending other groups to test it clinically.
