Does 3D Ultrasound Enhance the Diagnosis of Bladder Tumours in Patients with Haematuria?

Purpose. Bladder cancer is a frequent cause of haematuria in elderly patients, and bladder ultrasound (US) is a valuable tool in diagnosing these malignancies. We examined the accuracy of 3D bladder US in diagnosing bladder tumors in patients with haematuria. Patients and Methods. Twenty-one patients observed in the emergency department for haematuria underwent a kidney and bladder US. Patients with normal or uncertain bladder US findings underwent a 3D US and a cystoscopy. Results. In 5 (23.8%) patients, the 3D US detected bladder tumours not seen in 2D US. All these patients were found to have bladder tumours on cystoscopy. Another 5 (23.8%) patients with uncertain findings on 2D US had normal 3D US and cystoscopy. 3D US showed a sensitivity of 83.3% and a specificity of 100% with a positive predicted value and negative predictive values of 100% and 93.8%, respectively. Conclusion. 3D US was more sensitive than 2D US in diagnosing bladder tumours in patients with haematuria.

Transvesical peritoneoscopy with rigid scope: feasibility study in human male cadaver.

BACKGROUND: Transvesical port refers to the method of accessing the abdominal cavity through a natural orifice (i.e., urethra) under endoscopic visualization. Since its introduction in 2006, various reports have been published describing different surgical interventions using a rigid ureteroscope in a porcine model. The aim of this study was to test the access and feasibility of peritoneoscopy by using a rigid ureteroscope in a human male cadaver. METHODS: Two adult male cadavers were used to perform the procedures. A rigid ureteroscope was used for the creation of transvesical access into the peritoneal cavity. Peritoneoscopy, liver biopsy, and identification and manipulation of the ileocecal appendix were performed. RESULTS: Transvesical access into the peritoneal cavity was quickly established. The rigid ureteroscope easily allowed visualization of the abdominal cavity with good image quality. Liver biopsy and manipulation of ileocecal appendix were carried out without difficulties. CONCLUSIONS: Peritoneoscopy, liver biopsy, and ileocecal appendix manipulation using a rigid ureteroscope through a transvesical port is feasible in a cadaver model. The development of a specific rigid scope for the transvesical port might herald a promising future for this NOTES access.

[Bladder exstrophy adenocarcinoma in an adult woman. Case report]. / Adenocarcinoma sobre extrofia vesical en mujer adulta. A propósito de un caso.

OBJECTIVE: To report a clinical case of bladder exstrophy adenocarcinoma. METHODS: 57-year-old female presenting with a hypogastric mass. The biopsy of the mass revealed bladder adenocarcinoma. We performed radical cystectomy. RESULTS: Pathologic study was compatible with moderately differentiated adenocarcinoma. CONCLUSIONS: After six months of follow-up patient is disease-free.

OBJETIVOS: Aportamos un caso clínico de adenocarcinoma sobre extrofia vesical. METODOS: Paciente de 57 años de edad, a la exploración física evidenció una tumefacción hipogástrica. Efectuamos biopsia de la masa revelando adenocarcinoma vesical. Realizamos cistectomía radical. RESULTADOS: El estudio anatomo-patológico de la masa fue compatible con un adenocarcinoma moderadamente diferenciado de la vejiga infiltrando muscular. CONCLUSIONES: La paciente a los 6 meses se encuentra libre de tumor (AU)
