Filter by:This study prospectively included 178 patients with bladder neoplastic lesions who planned to undergo surgery (with or without preoperative neoadjuvant chemotherapy). Inclusion criteria: Patients with pathologically confirmed bladder cancer after radical or partial cystectomy or TURBT (< 2 weeks between surgical resection and imaging). Exclusion criteria: 1) Prior history of chemotherapy and/or radiotherapy; 2) No surgical resection; 3) The interval between surgical resection and imaging examination is > 2 weeks; 4) Obvious artifacts; 5)MRI scan contraindications. All subjects underwent pelvic MRI. Data was collected using a Siemens VIDA 3TMR scanner (Siemens Healthcare, Erlangen, Germany). All subjects underwent standardized scanning protocols. The obtained images are post-processed and the experimental results are analyzed statistically.
The purpose of the present study was to find out the difference in current intensity required for nerve stimulation according to the presence or absence of neuromuscular blockade during the obturator nerve block procedure for TURP.
Comparison of the obturator nerve block in patients undergoing transurethral resection due to bladder tumor, technically using ultrasound guided or blinded with anatomical signs.
Modified en bloc resection is a hybrid technique involving piecemeal resection of the exophytic part of the bladder tumour, followed by en bloc resection of the tumour base. In this study, we shall investigate the efficacy of modified en bloc resection for patients with bladder tumours of ≥3cm in size.
This is a prospective, multicenter, single-arm, open-label clinical usability study in subjects who are candidates for office diagnostic cystoscopy. The primary objective of this initial device assessment is to evaluate the performance of a new cystoscope for direct visualization of the urethra and bladder.
The aim of the study was to evaluate the safety and effectiveness of spinal anesthesia among elderly patients The basic methods for diagnosis and management of bladder cancer include endoscopic procedures (cystoscopy, trans-urethral resection of bladder tumour TURBT). The age of most patients is above 60, which increases the risk of complications during the perioperative period. Usually the leading anaesthesia method in TURBT procedures is regional, mainly spinal, anaesthesia. Although the prevalence of regional upon general anaesthesia is questioned, certain positive aspects of regional anaesthesia are indisputable. Maintaining logical communication with a patient during the procedure enables early diagnosis of complications (TUR syndrome, bladder perforation). Undeniably, regional anaesthesia ensures the best pain management in the early post-operative period. The simplicity of performing an efficacious spinal block and its cost-effectiveness are additional factors, which have contributed to the acknowledgement of the method as the standard of anaesthesia for transurethral procedures.
This study evaluates the influence of premedication on cognitive functions in patients undergoing transurethral resection of bladder tumor under spinal anesthesia. The aims of premedication are anxiolysis, analgesia and the reduction of perioperative risk among the patients with comorbidities. The patients will be randomly allocated to receive premedication either with opioid solely or with benzodiazepine combined with opioid. The anesthetic technique is standardized.
