“…Most of the embolization events are clinically asymptomatic. Only rarely have reported cases presented with presumed complications related to embolization or radiation-induced soft tissue damage: cardiac arrhythmias from right ventricular migration, acute myocardial infarction from right coronary embolization, and radiation pneumonitis from pulmonary relocation (3,7,12). We do not know if our patients' symptoms are attributable to the seed migration.…”

“…Although it has been reported that most patients with seed migration are asymptomatic, there have been a few reports of seed migration-related sequelae, such as a few anecdotal instances of cardiac arrhythmia, myocardial infarction, and radiation pneumonitis [21,36,37]. Therefore, it is important to try to reduce the incidence of seed migration.…”

BackgroundThe aim was to determine the incidence of seed migration not only to the chest, but also to the abdomen and pelvis after transperineal interstitial prostate brachytherapy with loose 125I seeds.MethodsWe reviewed the records of 267 patients who underwent prostate brachytherapy with loose 125I seeds. After seed implantation, orthogonal chest radiographs, an abdominal radiograph, and a pelvic radiograph were undertaken routinely to document the occurrence and sites of seed migration. The incidence of seed migration to the chest, abdomen, and pelvis was calculated. All patients who had seed migration to the abdomen and pelvis subsequently underwent a computed tomography scan to identify the exact location of the migrated seeds. Postimplant dosimetric analysis was undertaken, and dosimetric results were compared between patients with and without seed migration.ResultsA total of 19,236 seeds were implanted in 267 patients. Overall, 91 of 19,236 (0.47%) seeds migrated in 66 of 267 (24.7%) patients. Sixty-nine (0.36%) seeds migrated to the chest in 54 (20.2%) patients. Seven (0.036%) seeds migrated to the abdomen in six (2.2%) patients. Fifteen (0.078%) seeds migrated to the pelvis in 15 (5.6%) patients. Seed migration occurred predominantly within two weeks after seed implantation. None of the 66 patients had symptoms related to the migrated seeds. Postimplant prostate D90 was not significantly different between patients with and without seed migration.ConclusionWe showed the incidence of seed migration to the chest, abdomen and pelvis. Seed migration did not have a significant effect on postimplant prostate D90.

“…Miura et al reported a case of radiation pneumonitis caused by a single seed migration to the lung after brachytherapy. 10 In the present case, the seed might have been displaced to the bladder wall, persistently affecting the bladder wall. However, we did not find any evidence of seed migration on abdominal X-ray and postplan CT.…”

This report describes an extremely rare case of severely contracted bladder developing after prostate brachytherapy. In April 2001, a 76-year-old man initially presented to our hospital for weak urinary stream. The patient was diagnosed with and treated for benign prostatic hyperplasia. During follow up, prostate-specific antigen level was elevated. In November 2005, the patient underwent transrectal prostate biopsy. Pathology showed adenocarcinoma, Gleason score 3 + 4 = 7. The patient was diagnosed with stage cT1cN0M0 prostate cancer. In January 2006, he underwent brachytherapy for prostate cancer. The procedure of brachytherapy was uneventful and the patient was discharged without any problems. Four months after the implant, the patient was admitted to our hospital for deterioration of kidney function as a result of a contracted bladder. Urinary culture of tuberculosis was negative and urinary cytology was class II. A urethral catheter was indwelled and the patient has been followed every month for catheter replacement. Bladder capacity is now less than 5 mL.
