Can a man wearing a catheter Dukhen (say the priestly blessing) or get an Aliyah?
ADDITIONAL INFORMATION: The catheter drains urine through tubing to a bag attached to the body. Everything is hidden under clothing. The catheter must be emptied and cleaned on a regular basis (which can be done prior to the Aliyah or Dukhening) but it is possibly (likely?) that some remnant of urine would remain in the tubing.
Would potential answers differ depending upon whether or not the person can control his urine while engaged in the holy acts? How about if it is certain that the entire system can assuredly be 100% clean?
Thank you.
