Will Looking at or Touching the Satr of a Sick peson Nullify the Wudhu?

Q: Taharaat-36: If a Muslim doctor had wudhu and then looked at or touched the Satr of a patient, can he perform salaah with the wudhu?

Answer: If anything such as urine, Madhi, Wadi or semen was discharged from the front organ at the time of looking at or touching the patient, the doctor's wudhu will be nullified, otherwise not. Merely looking at or touching such areas will not nullify the wudhu, but it will be better to repeat the wudhu (or to at least wash the hands). And Allaah knows best what is most correct.
