[Relevance of clinical and serum parameters on severe urinary sepsis after renal obstruction.].

Introduction: Urosepsis is an underdiagnosed entity with high morbidity and mortality and significant associated costs. The delay in diagnosis leads to an increased risk of multiorgan failure and death. Although its prognosis is better than that of other sepsis, the mortality rate is 20 - 40%.

Primary and metastatic renal hemangiopericytoma.

Objective: Haemangiopericytoma is an uncommon perivascular tumor that occurs more frequently in soft tissues and is extremely rare in the kidney.

Methods: We report two cases: The first one is the case of a 57-year-old man with bilateral metastatic renal haemangiopericytoma which appeared 18 years after removal of a meningeal haemangiopericytoma. The second is a 29-year-old woman with a primary kidney haemangiopericytoma that was casually found in a nephrectomy piece.

[Squamous cell carcinoma in a duplicated renal pelvis after percutaneous nephrolithotomy].

Objective: To describe the clinical case of a patient presenting a squamous cell carcinoma in a duplicated renal pelvis, after percutaneous nephrolithotomy.

Methods/results: 60-year-old male patient who was diagnosed of a squamous cell carcinoma of the renal pelvis in the pathological study of a lower pole nephrectomy after percutaneous nephrolithotomy for staghorn calculi in the left lower pole renal moiety. The patient suffered a bladder recurrence one year and a half later.

[Solitary skin metastasis from a bladder carcinoma].

Cutaneous metastases from urothelial carcinomas of the bladder are very rare. They are related to advanced stages of the disease and have poor prognosis with low survival rates. We report one case of cutaneous metastasis appearing after urological manipulation in a patient with bladder muscle invasive carcinoma, with other metastatic sites and poor response to treatment.

Primary small cell carcinoma of the ureter.

We report a case of primary small cell carcinoma of the ureter. These tumors are very rare, locally aggressive and with poor prognosis. A 77-year-old man presented with left flank pain and microhematuria.

[Renal hydatidosis].

Objective: Our purpose is to report a case of renal hydatidosis and its treatment.

Methods: The characteristics of the case are presented and discussed.

Results And Conclusions: The hydotic disease is a parasitic infestation caused by the larvae from echinococcosis granulosus.

[Pelvic recurrence after radical cystectomy for bladder cancer].

Objectives: We report the case of a male patient who had undergone radical cystectomy and orthotopic neobladder for bladder cancer presenting with local recurrence eight months later.

Methods: Diagnostic tests included CT scan and ultrasound guided transrectal biopsy

Results: With the diagnosis of local recurrence he underwent chemotherapy and radiotherapy

Conclusions: The pelvic recurrence of transitional cell carcinoma after radical cystectomy is rare and prognosis is poor. It is frequently associated with advanced tumor stage.
