AIM To report the difference in the bladder and rectum doses with different applications by the radiotherapists in the same patient of the carcinoma of the uterine cervix treated by multiple fractions of high-dose-rate (HDR) intracavitary brachytherapy (ICBT). MATERIALS AND METHODS Between January 2003 to December 2004, a total of 60 cases of the carcinoma uterine cervix were selected randoml...

background: the most efficient application of ionizing radiation is serving medical purposes and using this radiation has caused people to learn that artificial sources of radiation exposure among these resources can be of highest exposure rate.   objective: the present study is aimed at initially establishing a baseline for local-reference dose level in mazandaran, iran in 12 projections of th...

background: to analyze the dosimetric and radio biologic advantages between intensity modulated radiotherapy (imrt) and 3 dimensional conformal radiotherapy (3dcrt) and selection of optimal photon energy for imrt treatments. material and methods: 24 patients with localized prostate carcinoma were planned for 3dcrt and imrt techniques. radiation dose of 54 gy with 2 gy/fraction, was planned to p...

PURPOSE Encrusted cystitis is a rare chronic inflammatory disease characterized by calcified plaques of the bladder, previously altered by varies conditions as urological procedures, caused by urea-splitting bacteria. Only one case has been reported on encrusted cystitis occurring after surgery and radiation therapy for a pelvic neoplasm. We report on encrusted cystitis occurred after definitiv...

we describe bladder and urinary tract abscess with concomitant hip arthritis in a 64-year-old male patient on hemodialysis. the patient recovered promptly after abscess draining and antibiotics. this case is reported with a brief discussion of risk factors of this condition.

PURPOSE To assess the safety, tolerance, and efficacy of transurethral surgery plus concomitant cisplatin, 5-fluorouracil (5-FU), and radiation therapy in conjunction with selective bladder preservation in patients with muscle-invading bladder cancer. Patients and Methods. Thirty-four eligible patients with clinical stage T2-T4a, Nx M0 bladder cancer without hydronephrosis were entered into a p...

Objective: To carry out dosimetric comparison between volumetric modulated arc therapy (VMAT) and intensity-modulated radiation (IMRT) in cervical cancer. Methods: 50 postoperative cancer patients were included this study. The admitted for treatment from January 2021 to 2022. VMAT IMRT plans designed each patient analyze the dose distribution target area of two techniques. Results: Comparing mo...

Introduction: In vitro dosimetric verification prior to patient treatment plays a key role in accurate and precision radiotherapy treatment delivery. Since the human body is a heterogeneous medium, the aim of this study was to design a heterogeneous pelvic phantom for radiotherapy quality assurance. Material and Methods: A pelvic phantom was ...
