Photoselective vaporization of the prostate with 120W HPS Greenlight laser is one of the most attractive modalities of surgical treatment for benign prostatic hyperplasia at present. The specific physical characteristics of this laser provides an excellent safety and effectiveness profile, making it the ideal technique for high-risk patients or patients ongoing oral anticoagulation. Moreover, the undeniable reduction of urethral catheterization time and hospital stay compared to transurethral resection of prostate (TURP) involves a much more comfortable postoperative period for patients. We have conducted a Medline/Pubmed search, presenting in this review the outcomes and current surgical techniques described in recent studies. We have also reviewed the controversial aspects and limitations attributed to this technique.

The Brucellosis is a zoonotic and unfrequent infection but it is endemic in Spain. It is a well documented cause of fever of unknown origin with varied and nonspecific symptoms. The onset of symptoms of brucellosis may be abrupt or insidious, developing over several days to weeks. Virtually any organ system can be involved with brucellosis and localization of the process may cause focal symptoms. The most frequent focal presentation is the osteoarthicular. Some times it can complicates with para-perivertebral abscess. The unilateral psoas abscess(PA) is uncommon and the bilateral afection is exceptional. The manifestations of PA usually are insidious, the classic tiad of: feber, lumbar pain and functional impotence is rare. For the diagnosis the serology c tests and cultures are necesary. The imaging techniques like: Ultrasonography and Tomography have improved the diagnosis and treatment of this pathologies' complications. The recommended therapy is the use of doxycicline and streptomicine. Some times the use of percutaneous drainage or open surgery is necessary.

Objective: To evaluate, in a retrospective analysis, our long-term results of patients undergoing the Essed plication procedure for the correction of penile curvature due to Peyronie's disease., Methods: Between January 1998 and June 2003, 83 patients with acquired penile deviation were treated with the Essed technique in our hospital. We analyse the following data: age, main complaint, type of deviation, erection before and after the surgery, physical exploration, ecographic data, complications and results., Results: Mean follow-up was 36 months. Main complaint was penile curvature in 96.3% of patients. The most frequent types of deviation were dorsal (55.4%) and left lateral (48.1%). Erection before surgery was sufficient for sexual intercourse in 74.7%. Physical exploration revealed a plaque in 79.5% of the patients. 93% of the cases reported complete penile curvature correction or residual deviation < 10 degrees. 65.1% of the patients were satisfied or very satisfied with the result of the operation and 64% were able to perform sexual intercourse., Conclusions: The Essed plication is a simple and minimally invasive method for correcting acquired penile deviation. Although functional results seem to be satisfactory, in our experience the degree of satisfaction with the outcome is not as good, among the patients, as it could be expected.

Objectives: The epidermoid cyst of the testis is a rare benign tumor. It accounts for approximately 1% of all testicular tumors. Generally, the testis has a palpable, painless mass with tumor markers (AFP, BHCG, and LDH) within normal ranges. Pathology reveals a cavity consisting of squamous epithelial cells containing keratin and non-nucleated keratic flakes in the absence of atypia or elements of teratoma., Methods/results: We report the case of a young man who was diagnosed of epidermoid cyst after orchiectomy., Conclusions: Tumor enucleation would be a proper treatment when ultrasound studies suggest this diagnosis. However, we often perform orchiectomy due to a low rate of suspicion, non conclusive ultrasound studies, or due to the high percentage of malignant testicular tumors in this age range.

Objectives: To describe the most relevant features of matrix lithiasis, an infrequent type of lithiasis seldom reported since the generalization of extracorporeal shock wave lithotripsy., Methods: We report a clinical case and analyze the most important bibliography found by MEDLINE search (1950-1999). We will focus on the physiopathology and etiology of these stones to understand its development and the clinical presentation showed by these patients., Results: Matrix lithiasis is a very rare entity, described almost one century ago. It is mainly composed of lithiasis matrix, and the percentage of mineral content is really low in comparison with usual stones. Persistent urinary tract infection is another constant in these patients, which to some extent conditions the modification of the usual urinary components, creating a series of the disturbances within the urinary tract that favour the aggregation of the components of the lithiasis matrix up to the formation of a stone, without need of aggregation of mineralized crystals., Conclusions: A high degree of suspicion is necessary for the diagnosis of matrix lithiasis, because it does not show the usual clinical picture of a renal stone. Exhaustive lavage of caliceal cavities and elimination of bacteriuria are essential elements for treatment, in order to avoid recurrence of the disease.

Objectives: To report a new case of renal colic in a patient with crossed renal ectopia and L-shaped kidney, and to perform a bibliographic review., Methods and Results: A 33-year-old male patient consulted for abdominal right pain. Ultrasound and CT showed a L-Shaped Kidney with left renal and ureteral stones. These stones produced obstructive left collecting system. This patient was managed with left pyelolithotomy and ureterolithotomy. The transabdominal approach was recommended to resolve this stones., Conclusions: The crossed renal ectopia with fusion is a rare condition. The abnormal kidney position and the anomalous kidney supply may impede drainage from the collecting system, creating a predisposition to urinary tract infection and calculus formation. The colic in this patient sometimes is misdiagnosed how abdominal disease. The usual method of detection was excretory urography but now ultrasonography and CT have showed more cases. The indications for open surgery in treatment the stones, are generally failure of extracorporeal shock wave lithotripsy, this is common in these cases for the anatomic abnormality, and the transabdominal approach is recommended to resolve its complications in this kidneys.

Objectives: To report a new case of neuroendocrine renal cell carcinoma., Methods: We report the case of a 76-year-old woman with neuroendocrine renal cell carcinoma who underwent radical nephrectomy without any further adjuvant treatment. We performed a bibliographic review about this rare renal neoplasia of which there are less than 20 published case reports., Results: Patient is asymptomatic four years after surgery, although she has local recurrence., Conclusions: Small cell renal cell carcinoma is a very rare neoplasia, affecting people over the age of 60 years, large in size, and metastatic at diagnosis. It has bad prognosis, with short survival times. The most adequate treatment has not been determined due to the scarcity of published cases; the combination of surgery and chemotherapy is the most frequently used.

Objective: To analyze our experience with the management of retroperitoneal abscesses., Patients and Methods: A retrospective study was made of 66 patients with retroperitoneal abscesses treated at our hospital from January 1975 to July 2001 for the purpose of analyzing the diagnosis and treatment of these rare infections. In each case, we analyzed patient characteristics, abscess location and origin, predisposing factors, clinical presentation, microbiology, radiographic findings, treatment, and outcome., Results: In our series, the most frequent type of abscess was perinephric (45.4%), and the most frequent origin was the kidney (72.7%), generally renal lithiasis or previous urological surgery. Gram-negative bacilli were the microorganisms most often involved as causal agents of abscesses. CT had the best diagnostic performance (95%). Percutaneous drainage resolved the abscess in 86.3% of the patients in which it was used, compared with 87.5% for traditional surgical drainage. In 4 cases, the only treatment was administration of antibiotics. In all these cases the abscesses were smaller than 3 cm and patients were in good general condition. The mortality rate was excellent (1.5%), probably due to the low rate of comorbidity in our patients., Conclusions: Gram-negative bacilli were the most frequent microorganisms in our retroperitoneal abscesses. CT was the imaging technique that produced the most reliable and rapid diagnosis. Radiographically-guided percutaneous drainage was a safe and effective therapeutic alternative when used as definitive treatment or preoperatively.

Objective: To present 3 cases of primary abscess of the psoas muscle. The clinical features, diagnostic tests, treatment and outcome are discussed., Methods/results: Three patients that presented with fever and pain referred to the renal and/or iliac fossa are described. Physical examination showed psoas involvement in only one patient. Among the complementary tests performed, ultrasound demonstrated the abscess in one of the cases; the definitive diagnosis was made by contrast-enhanced CT. One of the cases was treated only with antibiotics while the other two cases were treated with CT-guided percutaneous drainage and appropriate antibiotic therapy., Conclusions: Psoas abscess is an uncommon pathology whose presenting features are usually unspecific. CT with contrast enhancement is considered to be the technique of choice for the diagnosis and to corroborate the resolution of the condition. Recently, the use of CT or US-guided percutaneous drainage has replaced surgery as the initial therapeutic approach for this condition.

Objective: The p21ras protein is encoded by the three ras genes (H-, K- and N-ras) and participate in the regulation of normal cell growth and cell differentiation. The objective of this study is to determine the expression of this protein in locally confined renal cell carcinoma, as well as its relations with different histopathological variables and their prognostic implications., Method: 58 renal cell carcinomas, in pT1-T3a N0 M0 (TNM 1997) stages, treated by radical or partial nephrectomy with curative intention. We analysed different clinical and anatomopathological variables, as well as expression of p21ras in paraffinated tissue, using immunohistochemical techniques., Results: The mean percentage of stained nuclei was 6.1%, with a range lying between 0 and 45%. We did not obtain statistically significant association between expression of p21ras and the tumour size (p = 0.698), the nuclear grade (p = 0.676) or the histopathological stage (p = 0.095). The survival analysis also did not show significant differences when we stratified the patients using the mean value of the sample as reference point (p = 0.134)., Conclusions: Expression of p21ras was not demonstrated to be related to any of the histopathological variables analysed: size, grade and stage, or with survival. Therefore, this protein does not appear to be related to the evolution of renal cell carcinoma.

Case report of a primary testicular lymphoma in a sixty-two years old man, presenting initially as an enlargement of the testicle as the only symptom. Orchiectomy of left testicle was performed, with the diagnosis of Non-Hodgkin B lymphocytic lymphoma. The treatment applied was CHOP, presenting poor evolution with cerebral metastasis. He dead twenty-five months later diagnosis.

The spontaneous extraperitoneal bladder rupture is an uncommon event and the diagnosis is very difficult. It is defined like the rupture of bladder wall in absence of traumatism or iatrogenic techniques. The extravasation usually is produced into the peritoneal cavity, because of the greater weakness of the vesical dome. The diagnosis is based on the retrograde cystography, being necessary the surgical treatment in the intraperitoneal rupture, while the extraperitoneal one, could be treated in a conservative way with a vesical catheter. Here we present a case of spontaneous extraperitoneal bladder rupture, with oliguria, abdominal pain and a right hypochondrius mass as clinic presentation. Due to this, the diagnosis was made by the TAC, in which it was appreciated a continuity solution in the anterior bladder wall, with a contrast extravasation through the anterior abdominal wall. The retrograde cystography confirmed the definitive diagnosis. The treatment followed was based on the keeping of the vesical catheter and antibiotherapy.
