Unusual clinical scenarios in Urology and Andrology.

This collection includes some unusual cases and how they were diagnosed and treated. Case 1: A case of a patient with primary hyperthyroidism presenting with a submucosal ureteral stone after endoscopic lithotripsy was described. After multiple endoscopic treatment, the stone was successfully removed by open ureterolithotomy recovering ureteral patency and normal renal function. Case 2: A case of burned-out testicular cancer with atypical lymphatic spread (stage II A) was presented. After right orchiectomy and complete remission of tumor markers, due to atypical metastases location and uncertain histology, the patient was treated with systemic therapy based on bleomycin, etoposide and cisplatin (PEB). At re-staging after chemotherapy computed tomography showed reduction of all node metastases and an observation protocol was proposed. Case 3: A patient was readmitted to hospital after 12 days from an uneventful Robot-Assisted Radical Prostatectomy (RARP) for prostate cancer due to lower abdominal pain plus abdominal distension, nausea and constipation not responsive to medical therapy. Computed Tomography showed colon and small bowel dilatation without any evidence of anatomical or mechanical obstruction. Laparoscopic abdominal exploration confirmed bowel distension without evidence of obstructing lesions. Ogilvie's Syndrome or acute colonic pseudo-obstruction (ACPO) was diagnosed. The patient fully recovered and was discharged six days after the procedure. Case 4: A case of recurrent Acute Idiopathic Scrotal Edema (AISE) was diagnosed on clinical signs together with the decisive help of pathognomonic ultrasound findings as the "fountain sign". Case 5: Small bilateral testicular nodules were diagnosed in a 30-years old patient undergoing scrotal ultrasound in follow up of acute lymphoblastic leukemia. Ultrasound guided testis sparing surgery was performed demonstrating Leydig cell tumors.
