Presents a case report of fatal bladder carcinoma in an HIV-positive homosexual man. Patient's presenting symptoms; Findings of the histological examination conducted on the tumor found in the patient's bladder; Etiology of bladder pathology in patients with HIV.

The author, disciple of Dr. Cifuentes, thinks about the influence and teaching of his professor emphasizing some features that specially marked us. We emphasize his capacity to observe reality, his meticulous reading of all tests, his analysis of all the information obtained, and his intellectual rigor in the elaboration of the diagnosis. His interest for the patient, his thoughts about bladder cancer or the importance of statistics, and the introduction and support of endoscopic surgery in Spain are outstanding features. It is also outstanding his defense of urology as a medical-surgical specialty. As a conclusion we have his best legacy: his thoughts, his books and scientific works.

Objectives: Transrectal ultrasound is the method that gives a direct image of the prostate, its limits, structural and morphologic anomalies, and anatomical relations. Therefore, prostate volume is easily determined, being the first step for the application of certain therapeutic procedures. Prostatic cryotherapy and brachytherapy have been developed over the last years as minimally invasive options for the treatment of prostate cancer. Transrectal ultrasound of the prostate has allowed the application of these technologies in the daily practice, guaranteeing high efficacy and safety indexes. Cryosurgery is the controlled freezing of tissues. Prostatic transrectal ultrasound is the only method able to show the real-time evolution of prostatic cryoablation, allowing the urologist to control the evolution of the ice ball and to reach the targeted anatomical structures guaranteeing the oncological objectives, and diminishing complications and sequels. Brachytherapy, as a local intraprostatic radiotherapy, needs exact volume and dose calculations before the implant of the radioactive source within the gland. With transrectal ultrasound of the prostate, ultrasound-tomographic cuts are made for prostatic volume calculation and planimetry Once dosimetry is completed, real-time transrectal ultrasound control is necessary to perform the implant of the needles loaded with the seeds. Today, prostate cryotherapy and brachytherapy would be inconceivable without transrectal ultrasound.

Objectives: To perform a bibliographic review of the main features of cryotherapy as a therapeutic option in the monagemente of prostate cancer and to report our initial experience., Methods: We employed the Endocare Fast-Trac system (Medipro) with 2.4 mm needles implanted in a single maneouvre without rack or transrectal U.S. transducer support. Two cycles of freezing thawing were employed, with apex backward movement when necessary. Freezing cycle duration was between 7-10 minutes or more. The Onik maneouvre--injection of saline into the Denonvillier's space-diminishes the risk of rectal injury and fistula allowing reaching posterior limits of the icaball beyond the prostatic capsule., Results: We treated 20 patients. Follow-up was between 3036 months. 58% of the patients had unilateral prostate cancer, 42% bilateral. In accordance to the classic definition 9 patients were classified as low risk of extraprostatic disease, 6 medium risk and 5 high risk; using number of positive cores as the criterion for risk 5, 6 and 9 were low, medium and high risk respectively. Per protocol prostate biopsies were performed in 18 patients 6, 12 and 24 months after treatment. Two patients underwent a second treatment due to persistence of cancer cells in the 6-month biopsy (11%). 3-month PSA nadirs after a total of 21 cryo treatments administered were < 0,2 ng/cc in 15 cases (78.9%), < 0.5 ng/cc in 17 (89.4%) and < or = 1.0 ng/cc in 18 (94.7%); it was over 1 ng/cc in only 5.6%. 30 month PSA for the same cutoff values was 27.8%, 50.0%, 66.6% and 33.3%, respectively. Prostate cancer cells were detected in the 12-month biopsies of 5.5% cases. All 24-month biopsies were negative., Complications: We observed scrotal edema, hematoma, perineal pain and constipation which lasted 2-3 weeks. 1 patient suffered injury of the mucosa at the prostatic urethra, which did not result in rectal fistula and was treated with bladder catheter for 3 months. 4 patients had erectile dysfunction before treatment. All others presented erectile dysfunction after treatment; 3 of them (20%) recovered rigidity enough to have intercourse over the 30 month period. No urethral sloughing or acute urinary retention appeared and all patients are continent., Conclusions: Prostatic cryosurgery is an effective, minimally invasive procedure for the treatment of prostate cancer with very low surgical risk, low morbidity and almost null mortality.

About 2% of adults have an urachal cyst. The diagnosis is usually made due to its clinical complications. We report an inusual case of acute urinary retention due to an urachal cyst, with hipogastric pain and anuria as initial syntoms.

Introduction: The TVT system is the most common surgical technique of female stress urinary incontinence, because of the simplicity. good clinical results and rare complications., Material and Methods: From april, 1999 to march. 2004, it has been done in our department 100 TVT systems with the revision of the result over the six following months. The average follow-up rate was 10.36 months (R: 1-54 months) and looses mean the 11% of the cases. All the patients presented stress incontinence and their average age was 56.6 years old (30-80). The 12% of the cases have been previously operated of urinary incontinence. 21 patients presented previous surgery of pelvic floor. In the 17% of the cases, TVT systems was associated to another surgical technique: 15% of them was operated of cystocele, 1% of them had surgical correction of rectocele, 1% of them had a strong surgery of pelvic floor, that included TVT system, correction of pelvic floor and hysterectomy., Results: We obtained 65% of successful cases, defined as objective confirmation of absence of looses from the observer and the subjective reference of the patient: 17% of clear improvement (clear decrease of looses from the patient and subjective improvement) and 7% of failure of the technique. The total percentage of appearance of novo post-surgery urgency is 9%. There were complications in the 12% of the cases: there were three cases of bladder perforation, two of them intra-operative and one of them deferred and associated to an infection of surgical wound; another three cases of residue in the immediate post-operative that were resolved with bladder catheterization: one case of acute urinary retention that was treated with bladder catheterization with suprapubic cistostomy: one case of chemical peritonitis corrected with a conservative treatment; two cases of vaginal extrusion of sling, which were resolved with the section of the outer sling; one patient presented a hipogastric hematoma resolved with conservative measures: and one patient presented pelvic discomfort with spontaneous resolution., Conclusions: We consider the TVT system as an effective surgical technique in the treatment of the female stress urinary incontinence. It is a simple technique with a short stay in the hospital and rare complications.

Renal cell carcinoma with inferior vena cava thrombus is relatively uncommon and complicates radical nefrectomy. During the past twenty years our hospital have substantially contributed to the surgical stratification of renal cell carcinoma with extension into inferior vena cava through different techniques. The reason for this article is to discuss the mote efficient and appropiate surgical technique for this pathology. We believe that the diagnosis of vena caval invasion and level of tumoral extension is based on radiological examinations and it is crucial for the success of the surgery. We consider that the use of vena caval filter applied preoperatively could prevent the risk of thromboembolism during and after the surgery. The use of prosthetic grafts is unusual, because the long standing obstruction caused by the tumor thrombus will develope extensive collateral circulation which works as a natural veno-venous bypass. Finally, we try to avoid the use of veno-venous and cardiopulmonar bypass with or without complete hypothermic circulatory arrest due to the high association with adverse outcomes and mortality.

Cryosurgery is an emerging technology consisting on controlled freezing of tissues. Good results, maintained in the long-term, have been referred in the treatment of prostate adenocarcinoma. A role as possible substitute of partial nephrectomy in the treatment of renal adenocarcinomas smaller than 4-5 cm is under research. There is no discussion that freezing destroys cellular machinery and triggers several events the final result of which is cell death by necrosis and apoptosis. The decrease of temperature makes extracellular liquid crystallize and creates a hyperosmotic environment, which induces water to go out of the cell producing intracellular dehydration. Intracellular ice is created with fast freezing speeds being attributed the most destructive effect on biological tissues with irreparable damage. In blood vessels, it directly induces endothelial cell death and mechanical lesions of the endothelium; the consequence is the formation of thrombi that obstruct the lumen of the vessel. In the post-thawing phase there is an increase in free radicals formation and neutrophil activity, which induces cellular membrane lipids peroxidation and new endothelium lesions. Tissue destruction is determined by: minimal temperature achieved, freezing speeds, freezing phase duration, number of freezing-thawing cycles provided, and distance to the freezing focus. As we move away from the freezing focus cells are affected in different ways, and there are several mechanisms proposed to explain the lethal action induced by temperatures higher than--40 degrees C. In our series pathologic findings were: necrosis, hemorrhagic areas either developed or not, fibrosis, hyalinization and increases in the relative number of hematic capillaries, microscopic calcifications, basal cells hyperplasia, and transitional or squamous metaplasia. Residual cancer is localized in the areas less affected by freezing. It should be emphasize the scarce morbimortality associated with the procedure. It does not require ICU admission or blood transfusions, no cerebral vascular accidents (CVA) or heart events have been described, and mortality is null, so that it is feasible in high surgical risk patients and without age limit.

Objective: Sacral root neuromodulation is an effective technique for the treatment of Chronic Micturition Dysfunction (CMD) refractory to conventional therapy. New indications such as chronic pelvic pain and interstitial cystitis are currently making their way within the urologic setting. Several groups of gastric surgeons are now choosing this technique for the management of rectal diseases (constipation, sphincter dysfunction). This paper contributes our experience in the treatment of patients with CMD and the comparative results at one year from implant in all patients., Material and Methods: From December 1998 through July 2003, 18 neuromodulation definite implants were performed. The main indication was CMD in 62.5% patients. Follow up of patients was done at one month and three months, and every six months thereafter. Follow up is conducted through a micturition diary and QoL questionnaire. Electrode implant in the first 16 patients was achieved by open surgery. The next 2 patients had the electrode placed by a percutaneous technique using the "Tined Lead" kit., Results: Results at one year after implant were compared in all patients. The total number of neuromodulation implants placed was 18, 14 (77.7%) of which were women and 4 (22.3%) men. Mean age was 52.56 years. Implant indication was CMD in 72.2% patients, mixed incontinence (urinary and faecal) in 22.1%, and interstitial cystic disease in 5.5%. Symptoms improvement at one year from implant, as determined by a micturition diary and QoL questionnaire was 76.4%. Clinical improvement was greater in patients with urgency symptoms than in patients with predominance of voiding symptoms.

Objectives: To perform a historical review of varicocele and male infertility with the aim to find descriptions that first related them. In parallel, we review the evolution of treatment for varicocele up to date., Methods/results: We refer to multiple authors and their treaties on Medicine, from first to 20th Century, in which descriptions of these pathologies are found, focusing on descriptions of the surgical technique for treatment of varicocele and their application in Spain., Conclusions: Varicocele was already described in treaties from the first century having bee of n its treatment predominantly surgical from the first description to our days. Not identified as a cause of infertility until late, by the end of the 19th century, it is the main indication for treatment nowadays. The surgical technique has suffered many modifications over time, both in the approach as in the "radicality" of a vascular ligature applied.

Objectives: To report one case of prostate carcinoma with metastasis to the corpora cavernosum., Methods: We report the case of a 79-year-old patient with the diagnosis of Gleason 9 prostatic adenocarcinoma who presented a hard lesion on the glans penis one year after starting androgen blockade. The patient underwent palliative TURP and biopsy of the lesion., Results: Pathology reported a penile metastasis of prostatic adenocarcinoma., Conclusions: Penile metastasis are rare, usually appearing in advanced stages of the primary disease; their treatment is palliative and should only be carried out in symptomatic patients.

Acquired cystic renal disease (A.C.R.D.) is a risk factor for the development of renal carcinoma in the patient's own kidney after renal transplant (R.T.), development of a primitive tumor in the renal graft is infrequent, but the presence of metastasis of an epithelial tumor is very rare. This is the second case reported in the literature of metastasis of an epithelial tumor in the renal graft and the first case described of renal cell carcinoma metastasis (R.C.C.) in the renal graft. This paper describes the case of a patient with a normally functioning renal transplant and A.C.R.D. who develops RCC in his own kidney, with metastasis in the renal graft.

Objectives: To report the 7th case of pararenal angiomyolipoma published in the world literature and to review the international bibliography., Methods: We report the case of a 46-year-old female with history of renal colic and a complex mass on radiological tests., Results/conclusions: Extrarenal retroperitoneal angiomyolipoma is a rare pathology with no more than 7 published cases. The diagnostic difficulty and radiological similarities with liposarcoma make surgery the treatment of choice.

Objectives: The objective of this article is to perform a comprehensive exposition of the various non-endourological treatment options for upper urinary tract tumors in order to set the bases to choose the most adequate surgical indication depending on tumors' and patients' characteristics; we consider the various surgical approaches, and the historic evolution from the classic indication established by Albarran (radical nephroureterectomy with bladder cuff) to the current ones more conservative. We also consider the role of radiotherapy and chemotherapy in the treatment of these tumors., Methods/results: We refer to the conclusions of various authors and their large series published in the literature, series considered classic already, and provide support adding our experience by reviewing 223 patients treated from 1977 to 2003 with a mean follow-up of 45 months (maximum 238 months)., Conclusions: We can state that it is acceptable to indicate less aggressive ways of treatment (nephroureterectomy without bladder cuff, distal or partial ureterectomy, and conservative operations) if the oncological radicality requirements are met, remembering that site, tumor grade and stage are determinant in the outcome.

Primary testicular lymphoma is an uncommon testicular tumour that accounts for no more than 9% of all testicular tumours in those series with higher incidence; testicular lymphoma as haematopoietic tumours are also rare accounting for just 1% of all lymphomas; but due to their highly malignant histopathology they may become highly aggressive tumours. Patient age at presentation is over 60 years old which makes it the most frequent tumour for this age group. There is no standard protocol to treat this malignancy due to lack of extensive series. We contribute one case and make a literature review discussing the current therapeutic trends for this disease.

Objectives: Cryosurgery is defined as in situ freezing of tissues. Criosurgery in the treatment of prostate cancer aims to: 1- Eliminate all the glandular tissues and completely destroy the adenocarcinoma, 2- With a minimum number of complications. a) Preserving neighbour structures: bladder neck, striated sphincter, and rectum. b) Preserving urethral mucosa to reduce the elimination of sloughing tissues., Methods: We describe the technique of prostatic cryosurgery including all innovations introduced during the last ten years. The map with the number and situation of the 6-8 crioprobes should be done in such a way that the iceball created around each of them overlaps the contiguous ones. Probe-mapping and icing strategy together get the prostate included in a unique, solid mass, in which temperature descents homogeneously and spreads out of its limits, so that intraprostatic and extraprostatic temperatures (sensors at the apex, Denonvilliers fascia and both neurovascular bundles) are below -40 degrees C., Results: The standardized technique is based on: Substitution of liquid nitrogen by argon. Use of 6 to 8 cryoprobes. The probes are properly inserted into the perineum percutaneously under transrectal ultrasound guidance. Ice ball evolution control by biplane transrectal ultrasound. Separation of the two layers of Denonvilliers' fascia by injection of saline solution. Real-time measurement of temperature descent. Minimal temperature lower than -40 degrees C Commercial ureteral heating system. Double cycle of freezing-unfreezing Administration of hormonal therapy during time enough to avoid the gland size to exceed 45-50 cc., Conclusions: We describe the most advanced technique for prostatic freezing, highlighting the basic requirements to achieve the objectives pursued. It has improved oncologic results, in relation to PSA and percentage of negative biopsies, and has dramatically reduced complications.

Objective: To present a series of 63 patients with urinary incontinence due to sphincteric incompetence who underwent the implantation of an AMS-800 artificial sphincter., Methods: From 1984 to December 2002 a total of 69 patients received this prosthesis, 63 of which were available for review. The cause of incontinence was sphincter incompetence in all cases, said secondary to prostate surgery, neurogenic bladder, post-traumatic urethral lesion, and epispadias. 52 of them were placed in the bulbar urethra, and 11 in the bladder neck. The cuff diameters varied from 4 to 10 cm and reservoir pressures from 51-60 to 71-18 H2O cm., Results: The complications that appeared, ordered by frequency, were: malfunction, infection and rejection or exteriorization, fistula, and unappropriate size. The total number of reoperations was 39 in 28 patients. Functional results were successful in 48 cases and failure in 15., Conclusions: The use of an AMS-800 prosthesis for the treatment of urinary incontinence due to sphincteric incompetence is effective but not without complications. The most frequent indication was following prostate surgery, being this group the one that obtains the best results. Patients with incontinence of neurogenic origin have the highest complication rate, and the worst results in relation to vascularization and tissue trophism abnormalities. In female patients we prefer other techniques that have similar results, are technically easier and more economic.

Objective: We report a recidive of penis carcinoma after 21 years of surgery., Methods: This is the case of a male of 85 years old, with partial penectomy; by epidermoid carcinoma. In physics exploration, that it displays excrecente lesion at level of gland of 1 month of evolution. Biopsy being the result of epidermoid carcinoma reason why is made. Total penectomy, a with cutaneus uretrostomy., Results: The histopathological study of the piece, confirm a epidermoid carcinoma well differentiated.

Objectives: To report one case of lithiasis transference from the donor associated with renal transplant., Methods: 53-year-old female with obstructive uropathy within the first post transplant month., Results/conclusions: Lithiasis transference after transplant is a cause of early obstructive uropathy after kidney transplantation. The low the incidence of lithiasis transference does not justify the performance of x-ray and/or ultrasound of the donor organ in terms of cost effectiveness. Extracorporeal shockwave lithotripsy is a valid therapeutic option on transplanted kidneys.

We report a new case of sarcomatoid renal cell carcinoma, in a male of 67 years old, with locoregional recidive four months after first surgery, with two episodes of retroperitoneal hemorrhage after second surgery. The objective of this work is to contribute a new case and of doing one revision.

Testicular torsion in adult, is an uncommonly etiology, but we should make differencial diagnosis in every person over thirty years old, with acute scrotum. The wrong diagnosis raises the incidence orchiectomy in adults for vascular etiology. We report a male of 74 years old with acute scrotum and review of the literature.
