Late at night, the urology ward of Wuhan Union Hospital transferred an old dad who could not urinate on his own and was told that the catheter in the emergency department was unsuccessful. After coming to the urology ward, the old man was unable to walk because of the pain and distension in his lower abdomen. The urologist quickly treated him and found that not only was the patient’s abdomen bulging due to large amounts of urine retention, but his penis was also significantly swollen, and the patient had symptoms of prepuce and prepuce, making it impossible to find the urethral opening. The patient was initially diagnosed as having a long-term prepuce, which caused adhesions and subsequently led to closure of the external prepuce and acute urinary retention. The patient’s condition was initially relieved after emergency circumcision and catheterization, and the patient was instructed to undergo circumcision at the clinic during the day. Acute urinary retention in elderly men is a common disease, mostly caused by urethral obstruction such as prostatic hyperplasia, and can be relieved by catheterization and medication control. In this case, surgical treatment was necessary to remove the excess foreskin. Patients who are circumcised and circumcised often lack attention because they have no obvious symptoms. Especially in elderly patients, they feel that they have been so many decades, there is no big problem, and they can’t afford to undergo another surgery in their old age. The actual above view is not advisable, after suffering from circumcision, prepuce because of long-term urine, foreskin scale of chronic stimulation, can make the foreskin glans mucosa edema, congestion, erosion, repeated cross-infection. At the same time, germs can also be brought into the female body through the sexual life of the couple. If the foreskin is embedded, it can lead to serious consequences such as necrosis of the foreskin glans. Studies have shown that on average, one in five men are circumcised; one in 20 men are circumcised. Therefore, patients first need to change their mindset that circumcision and prepuce are not rare and embarrassing and should actively communicate with their doctor to get the best treatment. In young children and young adults, early uncircumcision can help with genital development and improve sexual function. And in middle-aged and older patients, timely treatment of prepuce can reduce the incidence of penile cancer and can prevent it from harming the spouse. To sum up, circumcision and phimosis should be actively treated surgically regardless of whether they have obvious symptoms, young or old, to enhance the quality of life and prevent distant disease troubles.
