[The usefulness of virtual endoscopy and CT urography in the diagnosis of upper urinary tract tumors].

OBJECTIVES: Upper urinary tract (UUT) tumors are a relatively low incidence pathology which often represents a diagnostic challenge for the urologist, because several imaging tests are usually necessary to achieve the final diagnosis. Over the last years CT scan has suffered a notable development and nowadays, with the arrival of new image processing hardware and software, it is possible to detect small urothelial lesions and to perform 3-D urinary tract reconstruction and virtual endoscopic navigation. METHODS: Between January 2004 and June 2005 we performed a total of 15 examinations in 15 patients for the study of asymptomatic hematuria of probable upper urinary tract origin. The technique included three phases to obtain images: basal phase, vascular phase and excretory phase. Processing and image analysis was performed by one radiologist. RESULTS: A total of 10 tumors were diagnosed, with pathological confirmation in all cases. We did not register any complication secondary to the technique, and all patients tolerated well the exam. CONCLUSIONS: The CT urography is a safe, well-tolerated, highly sensitive and efficient imaging test, very useful in the diagnosis of renal and UUT pathology. It may become the only imaging test performed in the study of asymptomatic hematuria and the test of choice for the study of urological tumoral pathology.

[The treatment of hydrocele as ambulatory surgery].

OBJECTIVES: To evaluate the results of this surgical treatment of hydrocele over the first four years of integration of the Urology Department in the Major Ambulatory Surgery Unit in our Hospital. METHODS: From January 2000 to July 2004 we have performed 167 hydrocelectomies as ambulatory surgery in 152 patients (15 cases bilateral) with ages ranging from 16-87 years (mean 52.6). All procedures were performed under local anesthesia, using between 10-15ml of 1% lidocaine. The Lord's vaginalis plication technique was employed in 92% of the cases, leaving resection techniques for the remaining 8%, which presented certain degree of enlargement of the tunica vaginalis. We evaluated inclusion and discharge criteria, results, and degree of satisfaction by means of a questionnaire. RESULTS: Results are equivalent to those of inpatient surgery. Only one patient required admission to the hospital due to a postoperative complication, which was clearly independent of the ambulatory character of the process. Satisfaction with treatment was higher than 95%. CONCLUSIONS: Almost all patients with hydrocele are candidates to ambulatory surgery, significantly improving the cost-efficacy rate, without diminishing the quality of care or patient satisfaction.

[Orthotopic bladder substitution in the treatment of interstitial cystitis].

OBJECTIVES: To point out the efficacy of supra trigonal cystectomy with orthotopic substitution iliocystoplasty in the treatment of advanced interstitial cystitis (IC). METHODS: We study the results obtained in four women suffering IC nonrespondent to conservative treatment who underwent the procedure. All patients comply with classic diagnostic criteria of IC, presenting long-lasting symptoms, between 4 and 8 years (mean 5.6), and voiding frequency of near one-hour day and night. RESULTS: Mean postoperative follow-up was 32 months (18 to 56); post operative evaluation included clinical evaluation, ultrasound, urodynamic studies, and radiological tests. Suprapubic pain disappeared in all cases, as well as pre-op lower urinary tract symptoms, with good control of urinary frequency day and night being evident in the immediate postoperative period. All patients referred high satisfaction with the outcome. CONCLUSIONS: When conservative treatment fails, supratrigonal cystectomy with orthotopic neobladder substitution is a valid therapeutic option in IC patients who comply with classic diagnostic criteria.

[Symptomatic hydronephrosis during pregnancy].

OBJECTIVES: Hydronephrosis is common during pregnancy, affecting 90% of pregnant women. It is usually asymptomotic, but a small percentage of patients show clinical symptoms requiring treatment. We want to report our experience in the diagnosis and treatment of symptomatic obstructive uropathy in pregnant women. METHODS: We retrospectively evaluate the results obtained in 162 pregnant women suffering symptomatic hydronephrosis who received care at our department over the last 12 years. RESULTS: Conservative treatment was effective in most patients, 39 patients required more aggressive therapy. Thirty-five patients underwent insertion of a doubleJ catheter, 2 patients percutaneous nephrostomy, and another 2 ureteroscopy and extraction of ureteral lithiasis. CONCLUSIONS: The most frequent etiology of symptomatic hydronephrosis during pregnancy is external compression by the gravid uterus, followed by ureteral lithiasis. We consider conservative treatment as the treatment of choice, leaving ureteral double J cotheter insertion or percutaneous nephrostomy for the refractory cases. Ureteroscopy is a new diagnostic and therapeutic option when other less aggressive meosures fail.

[Management of male sterility in patients taking anabolic steroids].

OBJECTIVES/METHODS: To review the incidence of male infertility secondary to intake of anabolic products and our experience and outcomes with treatment. There is a variety of such substances (testosterone, nandrolone, stanozolol, etc.) in their intake may be unique or combinations, both orally or parenterally. Comparisons between patients and case series are difficult because of the hiding of this practice and various consumption practices and doses employed. RESULTS/CONCLUSIONS: Most of the patients recover normal spermatogenesis does by stopping intake of anabolic substances. The period of time until recovery is 6.35 months. Patients not recovering after six months were given tamoxifen 20 mg/24-hour, if having a normal or inhibited hypothalamus-hypophysis axis. Duration of abuse, doses, and anarchical consumption maderesponse to treatment with antiestrogen drugs or gonadotropins unpredictable in patients not responding to conservative treatment.

[Primary psoas abscess: report of 5 new cases. Review of the literature].

OBJECTIVES: We report 5 new cases of primary psoas abscess in this review. We describe the various pathogen agents involved in the development of this disease, as well as the etiopathogenesis, which is explained by several theories, being the most commonly accepted hematogenous dissemination from a septic focus. In the same way, we refer the most interesting clinical data and the value of current diagnostic tests, among which are abdominal x-ray (KUB), ultrasound, isotope scan, and CT scan, being this latter the ideal diagnostic test for these processes. METHODS: Retrospective study from 1985 to 2000, including a total of 5 patients with an average age of 48.2 years. RESULTS: 4 of these 5 patients were males, and two of them had documented history of addiction to parenteral drugs and chronic alcoholism respectively. All patients presented with lumbar pain, four of them with fever, 2 functional impotence and 1 mass effect. Four of them had increased white blood cells count; ultrasound was diagnostic in one case only, and CT scan in all 5. Blood cultures were positive in three cases, being Staphylococcus Aureus the germ isolated from the pus in four cases. The four patients treated had a positive outcome without recurrence to date. CONCLUSIONS: The reappearance of primary abscesses in young population with history of alcoholism or addiction to parenteral drugs. CT scan is the diagnostic tests of choice. Percutaneous drainage has good results and is less aggressive therapeutic option for this disease.

[Mesonephroid adenocarcinoma. Apropos of a new case and review of the literature].

OBJECTIVES: Mesonephric adenocarcinoma is a rare clinical entity, predominantly appearing in women, involved in great controversy about its histogenesis. Reported cases to date were not diagnosed in their initial stages and they were treated by radical surgery with poor results. METHODS: We report the case of a 71-year-old male with previous diagnosis of nephrogenic adenoma two years before. RESULTS: After the diagnosis of mesonephric adenocarcinoma was established, patient underwent radical surgery despite its poor prognosis. CONCLUSIONS: Differential diagnosis between these tumors should be made with primary or metastatic adenocarcinoma and nephrogenic adenoma. We highlight the ongoing controversy in the literature in relation to malignant evolution of the nephrogenic adenoma as etiology of the rare mesonephric adenocarcinoma. In this case, previous finding of a nephrogenic adenoma would support that theory.
