Extensive dystrophic calcification of eroded artificial urinary sphincter cuff-a rare cause of urethral obstruction: a case report.

Transl Androl Urol 2022 Apr;11(4):567-570

Cleveland Clinic Foundation, Glickman Urologic and Kidney Institute, Cleveland, OH, USA.

Background: Despite a high technical success rate and satisfaction, complications of an artificial urinary sphincter (AUS) can occasionally occur and vary in severity from transient urinary retention to unrecognized urethral injury or urethral erosion. Infection usually occurs when urine comes into contact with the device and necessitates explant of the cuff followed by delayed device replacement. In rare cases, however, the device can remain in contact with urine for long periods of time without the sequelae normally associated with acute infection. Read More

Prospective Evaluation of Prostate and Organs at Risk Segmentation Software for MRI-based Prostate Radiation Therapy.

Radiol Artif Intell 2022 Mar 26;4(2):e210151. Epub 2022 Jan 26.

Departments of Imaging Physics (J.W.S.), Radiation Physics (R.J.K.), Radiation Oncology (C.T., H.M., S.J.F.), Diagnostic Radiology (A.M.V.), and Biostatistics (H.D.T.), The University of Texas MD Anderson Cancer Center, 1515 Holcombe Blvd, Houston, TX 77030.

The segmentation of the prostate and surrounding organs at risk (OARs) is a necessary workflow step for performing dose-volume histogram analyses of prostate radiation therapy procedures. Low-dose-rate prostate brachytherapy (LDRPBT) is a curative prostate radiation therapy treatment that delivers a single fraction of radiation over a period of days. Prior studies have demonstrated the feasibility of fully convolutional networks to segment the prostate and surrounding OARs for LDRPBT dose-volume histogram analyses. Read More
