Persistence, recurrence, and progression rates of superficial bladder tumours after resection using the differentiated technique

To investigate whether the differentiated resection technique for excising superficial bladder cancer leads to higher recurrence and progression rates as compared with regular resection. We evaluated 163 patients, 66 undergoing a differentiated and 97 a regular resection. All patients underwent a routine second resection within 6-10 weeks. Recurrence and progression rates as well as tumour persistence on second resection were analyzed. Patients with differentiated resections of bladder tumours did not have higher tumour recurrence and progression rates. Also, these patients had a significantly higher percentage of tumour-free second resections [p = 0.03]. The differentiated resection technique for excising superficial bladder cancer has no negative influence on recurrence and progression rates, but it leads to a reduced tumour persistence

Diverticular carcinoma of the urinary bladder: diagnosis and treatment problems. A case report

To report a case of a primary carcinoma arising in a vesical diverticulum. Clinical Presentation and Intervention: A 59-year-old male patient presented with painless macrohematuria. A primary carcinoma arising in a vesical diverticulum was detected with cystoscopy and confirmed with rectal endosonography and computer tomography. and radical cystoprostatovesiculectomy with ileal conduit was performed. Chemotherapy with cisplatin and methotrexate followed. The patient died of an acute cardiac event in the 4th postoperative month.This report illustrates that in a case of a closed opening of a bladder diverticulum, rectal endosonography and computer tomography do provide additional support for making a diagnosis of a hidden tumor in the diverticulum
