Objectives: To define the different characteristics of transdermal oxybutynin (TO) for the treatment of overactive bladder in adults, to know the barriers for the use of this drug and to establish proposals to minimize these barriers.
Methods: Local sessions were held with 111 urologists from all over the country divided into 12 sessions. They were moderated by a brainstorming technique led by an external consultant.
Objective: To report one case of supernumerary testicle, a rare entity with around 100 cases published.
Methods: 44-year-old male patient consulting for incidental discovering of a right scrotal mass. The diagnosis of polyorchidism was suspected after physical examination, ultrasound, and CT scan, and confirmed subsequently on surgical exploration and biopsy.
Objective: Neurological metastases secondary to urological tumors account for 12% overall. The ones derived from germ cells testicular tumors are exceptional in the age of cisplatin.
Methods: We report one case of mixed germ cell tumor in a 49-year-old male patient treated with systemic chemotherapy during 18 months before presenting with severe central and peripheral neurological symptoms leading to death due to massive cerebral hemorrhage.
Objective: We report a new case of Sertoli cell testicular tumor with malignant characteristics.
Methods: 77 year-old male patient, suffering a general wasting syndrome presenting with a left solid testicular mass with the diagnosis of malignant Sertoli cell tumor after orchyectomy, without local, regional or distant dissemination, and a benign outcome after 18 months of follow-up.
Results: Sertoli cell tumor or androblastoma is classified as non-germ cell tumor derived from the stroma of the sexual cords.
Objective: Adenomatoid tumor of the epididymis is unfrequent, benign, with no malignant outcomes described.
Methods: We report five cases, with patient's ages varying from 31 to 76 years, and tumor sizes from 6 to 30 mm. All patients underwent surgery with excision of the mass, some of them after several months of growing.
Objective: To issue the existence of a variety of angiomyolipoma, named epithelioid, with different histological and clinic properties.
Methods: We report the case of a 17 year old female, with Bourneville's disease, who was discovered to have a solid renal mass suggestive of carcinoma in a control CT scan, adjacent to other smaller masses identified as angiomyolipomas.
Results: After several tumorectomies, the suspicious mass, 4 cm in size, was diagnosed as epithelioid angiomyolipoma, with immunohistochemical confirmation of capacity for HMB45, and negative vimentin and keratin.
Objective: To report one case of unusual testicular metastasis from a renal origin.
Methods: 57 year-old patient with disseminated right renal cancer under treatment who presented bone metastasis and a painful nodule in the upper pole of the right testicle during his follow-up with medical therapy, making surgery necessary. The pathology result was clear cell adenocarcinoma.
Objective: To report a new case of exceptional metastases from a prostatic carcinoma.
Methods: 64-year-old male with nine months history of disseminated prostate cancer, taking hormonal treatment and biphosphonates, who presents with rising PSA, facial dysesthesia and left exophtalmos. MRI recognizes the existence of a solid mass in the right maxillary sinus with involvement of the ipsilateral orbital floor, and another one in the left frontal sinus invading the roof of the ipsilateral orbit and also with orbital extraconal involvement.
