Purpose. - The aim of this prospective study was to investigate the effect of extracorporeal shock wave lithotripsy (SWL) on kidneys of patients with pyelic stone disease. The effects of SWL were assessed by high-resolution proton nuclear magnetic resonance (HNMR) spectroscopy of urine samples.Methods. - Twenty-three patients, aged 31-80 years (mean: 55 years), with pyelic stone disease were investigated before and after SWL. Multiparameter analysis was performed by HNMR spectroscopy of urine samples collected before and 5 h after SWL (second miction post-SWL).Results. - The most relevant resonances determined by HNMR spectroscopy were acetate, lactate, trimethylamine N-oxide and amino acids. Excretion of these markers increased significantly in comparison with pre-SWL urinary samples.Conclusion. - These results show that early ischemic damage occurs after SWL. Post-SWL. HNMR spectroscopy is an effective tool for noninvasive follow-up of renal damage. (C) 2011 Elsevier Masson SAS. All rights reserved.

The simultaneous presence of primary carcinomas in the same patient is uncommon and synchronous primary tumors involving the kidney and pancreas are extremely rare. There are a few reports in the English literature of synchronous primary malignancies of the kidney and pancreas. We present a 62-year-old man who had weight loss of 9 kg and epigastric pain. Findings showed a Furhman grade II renal papillary carcinoma confined to the kidney and a synchronous well differentiated pancreatic ductal adenocarcinoma.

The renocolic fistula is a rare entity, which has occurred exceptionally in a traumatic not iatrogenic context, we report a case of renocolic fistula complicating penetrating abdominal trauma from a gunshot.

The nutcracker syndrome refers to compression of the left renal vein between the aorta and the superior mesenteric artery. After a review of the literature, the authors emphasize the uncommon incidence of this pathology, and the interest of imaging in the survey of this affection.

Nutcracker syndrome is caused by compression of the left renal vein between the aorta and the superior mesenteric artery where it passes in the fork formed at the bifurcation of these arteries. The phenomenon results in left renal venous hypertension. The syndrome is manifested by left flank and abdominal pain, with or without unilateral haematuria. The nutcracker syndrome has been treated in various ways. We report one case of the syndrome and discuss the place of surveillance in its management.

Angiomyofibroblastoma of the scrotum is a rare and benign tumour which affect old patient. It's treatment is surgical. A case of angiomyofibroblastoma of the scrotum is reported in a 34 years old man. The literature is reviewed with special reference to the ethiopathogenesis, clinical features and treatment of this tumour entity.

Objective To report the natural history of 'burned-out' testicular tumour (a testicular tumour that has regressed spontaneously with no treatment and that generally presents at the stage of metastases).Patients and Methods We report five cases of burned-out testicular tumours to illustrate the clinical, radiological and histopathological features, and discuss the hypothesis of natural history of these neoplasms.Results The findings in the five patients tended to indicate that metastatic progression appears to induce spontaneous regression of the previous tumour site. Patients explored for extragonadal germ cell tumour present with various clinical features depending on the site of the metastases.Conclusion Despite the controversial hypotheses of the origin of these tumours, extragonadal germ cell tumours should be considered to be metastases of a 'burned-out' primary testicular tumour that must be investigated. When a primary testicular tumour is detected, the testis must be removed, and standard chemotherapy yields good long-term results. The hypothesis of an immunological reaction against the tumour inducing the spontaneous necrosis of the primary tumour and possibly the metastases should be considered. Immunological screening should be proposed in patients to investigate this interesting model of spontaneous tumour regression.

Urachal remnants are not exceptional and are symptomatics if complicated. Ultrasound and CT scan identify most diseases entities originating from urachal remnant. Treatment consists on total exeresis because there is a risk of malignant degeneration. The authors report a case of urachal remnant and analysis the anatomopathologic, diagnosis and therapeutic features of urachal remnants in a review of the literature.

Urinary tract involvement in neurofibromatosis type 1 is rare and uncommon entity. The syndrome is transmitted as an autosomal dominant trait and is characterized by cutaneous pigmentation and tumors as neural crest origin. Two cases of kidney involvement by Von rechlinghausen's disease with in one case a consequent hydronephrosis with arterial hypertension and in the second a nephrocalcinos without hyperparathyroidism are present. The literature of urogenital and nephrologic neurofibromatosis is reviewed. The authors suggest that the patient with neurofibromatosis be screened annually with medical history, physical examination, urinalysis and serum chemistry for tumors that affect the urinary particularly in children.

The authors report 2 cases of prostatic tuberculosis. The patients are 59 and 62-years-old respectively. They presented obstructive and irritative symptoms of the lower urinary tract. The prostatic finding and PSA were abnormals. The prostatic biopsy was negative. The diagnosis of prostatic tuberculosis was made by histologic analysis after transuretral resection of prostate. The treatment is based on chemotherapy anti-tuberculosis.
