Collateral urethral duplication in an adult.

OBJECTIVE: Congenital anomalies or malformations of the urethra that involve number are extremely rare and only 7 cases of trifurcation of the urethra and under 500 cases of urethral duplication have been described. METHODS: In the case we present, urethral duplication was diagnosed in adulthood, even though glans malformation with 2 urethral orifices was clearly evident and only 1 was functional. RESULTS: The condition is usually diagnosed in childhood due to the presence of 2 urethral meatus or from double stream if both are functional; at other times, the condition is diagnosed from complications that trigger infections or obstruction or if it is associated with more extensive malformations. CONCLUSIONS: Urethral duplication is an extremely rare birth defect, and diagnosis in adulthood is even more uncommon. No single embryologic argument explains all the anatomic variants of urethral duplication. The treatment of the urethral duplication should be individualized according to the type of duplication and the clinical symtoms.

Penile foreign bodies.

OBJECTIVE: To describe 8 cases of penile foreign bodies. METHODS/RESULTS: We provide an essentially visual overview of various objects or foreign bodies affecting the penis. CONCLUSIONS: The presence of penile foreign bodies is rarely due to an accident. These objects are placed for a wide variety of reasons, but primarily for erotic or self-arousal purposes. The consequences of penile foreign bodies can be mild or very severe, resulting in penile amputation.

[Saturation biopsy in prostate cancer diagnosis]. / Biopsia por saturación en el diagnóstico de cáncer de próstata.

AIMS: To analyze the results obtained after doing saturation prostate biopsy to a series of patients with high level of PSA. SUBJECTS, MATERIAL AND METHOD: Among 2006 and 2007 saturation biopsies have been realized in our Service to 32 patients with high PSA, previous biopsies without diagnosis of prostate cancer and high suspicion of malignant disease. RESULTS: The mean age was 65.81 years, with an average of previous biopsies of 2.41 (range: 1 to 5). Mean of PSA was 15.45 ng/dl (range: 5.63 to 35.47 ng/ml). The mean number of cores obtained in the saturation biopsies was of 20.78 (range: 16-26). 13 were diagnosed prostate adenocarcinomas (40.63%), of which 10 had previous diagnosis of PIN or atipia. 8 patients underwent radical prostatectomy, 3 cases were treated with radiotherapy, 1 case was treated with hormonetherapy and the remaining one is kept in watchful waiting. Concordance of Gleason grade was in 6 of 8 patients treated surgically. CONCLUSIONS: Saturation biopsy is an effective method for the diagnosis of prostate cancer after several negative biopsies and a strong clinical suspicion of malignant pathology. Saturation biopsy is not a first choice procedure for the diagnosis of prostate cancer.

[Fracture of the penis: a case series]. / Fractura de cuerpos cavernosos. Serie de casos.

Penile fracture is an uncommon urological emergency with a typical presentation, which needs early surgery to avoid aesthetic and functional sequelaes. We have analyzed all the patients with a discharge diagnosis of fractures penis among 1997 to 2007, attended in the emergency service of Complejo Hospitalario Universitario de Albacete, showing its clinical features, attributed mechanism of injury, treatment and main complications.

VHL protein alterations in sporadic renal cell carcinoma.

AIMS: The vhl gene is a tumour suppressor gene implicated in renal tumorigenesis in both familial and sporadic renal cell carcinoma (RCC). Alterations in the gene may modify its suppressor function and allow the formation of renal tumours. The purpose of this study was to determine the existence of vhl gene mutations in renal tumour tissue among patients with sporadic RCC and to assess the effects on the structure of the VHL protein. MATERIALS AND METHODS: This was an observational, analytical and descriptive study of 96 patients who had undergone surgery for sporadic RCC. In surgical specimens of tumour tissue, the three exons of the vhl gene were amplified by polymerase chain reaction and subjected to automatic sequencing. The consequences of the mutations detected on the VHL protein were analysed, taking into account the physical and chemical properties of the amino acids changed by the mutations, the location of the alterations in the protein sequence, the degree of conservation throughout evolution, and prediction of the secondary structure of the protein. RESULTS: In total, 22 vhl gene mutations were detected in 21 (21.9%) patients; in particular, 13 exonic point mutations consisting of 11 sense mutations, one silent mutation and one missense mutation, plus five exon deletions and one insertion. The remaining three were intronic mutations. All changes occurred in protein functional domains and in regions that have been well conserved throughout evolution. Two-thirds of the intronic mutations were considered relevant for protein function. Among the mutations detected, 72.7% were considered capable of compromising the VHL protein suppressor function. CONCLUSIONS: Mutations in the vhl gene result in amino acid changes in the protein that usually occur at important functional sites that have been conserved throughout evolution and where the binding domains for other proteins are located and exert their suppressor function.

Late recurrence of ovarian granulosa cell tumor at the retroperitoneal and renal hilum level in a single-kidney patient--case report.

BACKGROUND: Ovarian granulosa cell tumors are rare tumors characterized by a long natural history and a tendency to late recurrence. Surgical resection, radiotherapy, chemotherapy and hormone therapy are possible options to treat recurrent disease. The choice will depend on the patient's condition and the site of recurrence. CASE: We describe the case of a 72-year-old patient with a single left kidney who presented retroperitoneal recurrence of ovarian granulosa cell tumor at the left renal hilum ten years after primary treatment. CONCLUSION: This case illustrates an example of very late recurrence and emphasizes the importance of extended follow-up for these patients.

[Hemoperitoneum and death due to hepatoesplenic metastasis rupture in a testicular tumor]. / Hemoperitoneo y muerte por rotura de metástasis hepatoesplénicas de tumor testicular.

[Vesical schistosomiasis, case report and Spanish literature review]. / Esquistosomiasis vesical, aportación de un caso y revisión de la literatura española.

Urinary schistosomiasis is an infection caused by parasite, Schistosoma haematobium. Squistosomiasis is an endemic disease in Africa and Middle East. We are presenting a case of a young immigrant male from Mali that came to our clinic with hematuria and miccional irritative syndrome during a year. Parasitological study reported Schimosoma's eggs and ecography showed a possible vesical newformation. After RTU, anatomopatological study confirms the presence of a vesical esquistosomiasis. Now pacient is asyntomatic after he was treated with Praziquantel.

[Growing incidence in renal cell carcinoma]. / Incidencia creciente en el carcinoma de células renales.

OBJECTIVES: To analyze the change in the behavior of renal cell carcinoma for its presentation, treatment, histology and mortality during a 17 year period. MATERIAL AND METHOD: Retrospective study on 212 patients diagnosed with renal cell carcinoma in our Department from the year 1988 up to 2004, analyzing the clinical and demographic data and comparing them to each other according to two periods: 1988-1996 and 1997-2004. RESULTS: An increase has been appreciated in the incidence of renal tumors in the second period and in a same way an increase in the incidental diagnosis and in the practice of nephron sparing surgery. Clear cell type was the most frequent in both periods and tumoral size was higher in the first period than in second. TNM stage I was the most frequent, although in first period it was higher percentage of stage IV. Cause-specific mortality has increased in the last years. CONCLUSION: An increase is appreciated in the incidence of renal cell tumors. Although the diagnosis is in earlier stages, a descent in the mortality has not been found.
