[Kidney transplant urinary complications. Diagnosis and treatment.].

There are different surgical techniques for reconstruction of the urinary tract in kidney transplant. However, urinary complications are frequent in the postoperative period, being the ureter the frequent location of these complications. This results in high health care costs, increasing patient morbimortality and sometimes graft loss.

[Kidney cancer stage pT3a: Fat invasion versus renal vein invasion.].

Objective: We discuss the influence that involvement of fat (perirenal, sinus) and vascular structures (renal vein, segmental veins) have on cancer-specific mortality (CSM) rates in renal cancer.

Methods: We conducted a retrospective analysis of 140 stage pT3a kidney tumors (114 clear cell, 9 type I papillary, 6 type II papillary, 11 chromophobe) surgically treated between 1997 and 2015. We conducted a cancer-specific survival study (Kaplan Meier) and a univariate and multivariate analysis of the variables: perirenal fat invasion, sinus fat invasion, renal vein invasion, segmental vein invasion and Fuhrman grade.

Pseudomyxoma peritonei: A case report and review of the literature.

Objective: We present the case of a patient incidentally diagnosed with a pelvic mass next to the bladder. After surgical excision, definitive diagnosis was pseudomyxoma peritonei. We provide a concise review of the literature of this pathology.

[Oncological results in high grade prostate cancer treated surgically].

Objectives: Prostate cancer is considered a tumour with a long natural history. However, its high-risk variants exhibit variable behaviour. We analyse the factors that affect BR and CSS (multivariate, Kaplan Meier).

Biochemical recurrence risk factors in surgically treated high and very high-risk prostate tumors.

Introduction: High and very high-risk prostate cancers are tumors that display great variation in their progression, making their behaviour and consequent prognosis difficult to predict. We analyse preoperative and postoperative risk factors that could influence biochemical recurrence of these tumors.

Material And Methods: We carried out univariate and multivariate analyses in an attempt to establish statistically significant preoperative (age, rectal examination, PSA, biopsy Gleason score, uni/bilateral tumor, affected cylinder percentage) and postoperative (pT stage, pN lymph node affectation, Gleason score, positive surgical margins, percentage of tumor affectation, perineural infiltration) risk factors, as well as their relationship with biochemical recurrence (PSA >0.

Traumatic rupture of the corpus cavernosum: surgical management and clinical outcomes. A 30 years review.

Introduction: Penile trauma (PT) with associated rupture of the corpus cavernosum, also called penile fracture, is a urological emergency and surgical treatment is usually the choice of management. Our objective is to report our experience after 30 years in the diagnosis and therapeutic options of PT and evaluate the clinical outcomes after the treatment.

Material And Methods: From January 1983 to January 2013, 27 patients were identified.

Incidence and management of isolated renal injury and polytrauma patients.

Objectives: The management of renal trauma has undergone important changes in recent years, the current tendency being more conservative than in the past. The present study analyzes our experience over the last 11 years in patients with isolated renal trauma or associated to other lesions.

Methods: Over an 11-year period (January 2001- December 2011 ) we documented a total of 149 renal injuries (47 isolated and 102 associated renal lesions ).

[Adenomatoid tumors of the epididymis and testicle: report of 9 cases and bibliographic review].

Background: To report the cases of adenomatoid tumors seen at Hospital Universitario La Paz in the last 15 years.

Methods: A clinical, pathological, and surgical study was conducted of males with testicular or paratesticular tumors with a histological report of adenomatoid tumor.

Results: Among the nine cases studied, seven had paratesticular and two intratesticular adenomatoid tumors.

Urinary tract endometriosis: clinical, diagnostic, and therapeutic aspects.

Objectives: To describe our experience at La Paz University Hospital with 12 patients with urinary tract endometriosis, an uncommon pathologic finding, the most extensive series published by Spanish investigators to our knowledge.

Methods: We performed a retrospective analysis of 12 cases of urinary tract endometriosis diagnosed from 1993 to 2008.

Results: The mean patient age was 37.

[Early-onset sarcomatoid renal carcinoma. Report of a new case and comparison of the same case with another appearing at a mature age].

Objective And Methods: We report two new cases of this rare and aggressive tumour; one case appeared in the earliest age reported in the literature (case #2). We also review etiological, diagnostic and therapeutic features.

Results: Despite aggressive surgery and adjuvant chemotherapy it has a very poor prognosis, with disease progression within 6 months in both cases.

[Mesothelial cysts in urology: a diagnostic and therapeutic problem].

Objective: To present our experience with mesothelial cysts with excretory system involvement.

Methods: 3 cases of mesothelial cyst are presented; two of them caused obstructive uropathy.

Results: Cases 1 and 2 were treated by surgery, while case 3 was managed conservatively.
