Atypical Renal Cysts: Is MRI a Compulsory Examination in 2020 before Therapeutic Management?

Introduction: Kidney cancer represents 2% to 3% of malignant tumors, with an incidence of 5.8/100,000 in Western countries, a very specific subgroup of renal tumors that are cystic tumors. In fact, almost 50% of the population over 50 has a renal cyst. Materials and Methods: The objective of this study is to establish a correlation between the preoperative Bosniak score and the postoperative anatomopathological analysis in order to answer this question, the use of contrast ultrasound or MRI should be systematically performed before an atypical renal cyst? This is a retrospective study of 50 patients treated for renal cysts between January 2010 and March 2016. All patients have an abdominopelvic ultrasound and an abdominal scanner. Cysts have been classified according to the Bosniak classification. We treated our patients based on the radiological examination urocsanner and we classified our patients according to the classification of Bosniak, and uro MRI was performed in cases of atypical cysts or diagnostic doubt before considering a therapeutic attituderding to the classification of Bosniak. Results: In our work, the Uro MRI was sharper for atypical cysts (type IIF and Type III cyst) with sensitivity greater than that of the scanner but with a specificity similar to that of the scanner. And therefore be a key examination in the atypical kidney cysts. Conclusions: URO MRI is currently in 2020 a key examination of atypical bonsiak IIf and III cysts before management of the therapeutic load.

Urethral Stone: A Rare Cause of Acute Retention of Urine in Men

Urethral stones are a very rare form of urolithiasis, they most often originate from the upper urinary tract or bladder, and are rarely formed primarily in the urethra, it is formed on a urethral anatomical pathology in the majority of cases. The clinical symptomatology is very variable ranging from simple dysuria with penile pain to acute retention of urine. Smaller stones can be expelled spontaneously without intervention, but larger stones or complicated stones or those developed on an underlying urethral anatomical pathology require surgical treatment. The minimally invasive treatment should be the preferred route for the surgical treatment of this disease when feasible. We report the case of a young man with no particular pathological history who presented to the emergency department for acute retention of urine secondary to a primary fossa navicularis calculus, through this case, we discuss the different clinical aspects, etiology, pathogenesis, diagnosis and therapy of urethral stone in men.
