The father of a classmate had an attack of kidney stones and pain in the lower back and abdomen, and was treated with antispasmodic (654-2) and symptomatic therapy for 3 days in the local hospital, but after the pain was relieved, there was difficulty in urination, and he had to go to the hospital for catheterization again. Cystoscopy, found bladder stones, removal of the stone was given anti-inflammatory, symptomatic treatment for 1 week, urine still can not be self-extraction. Ultrasound of the prostate did not reveal any abnormality, and urodynamic examination suggested that the contraction of the urethral muscle was weak. He was treated with anti-inflammatory and continuous catheterization for nearly 20 days, but his symptoms were not relieved. The doctor was ready to do cystostomy for him. Although it was a minor surgery, it required urinary diversion, which brought a great psychological burden to the patient. The patient and his family were reluctant to accept it. At this time, my classmate remembered me working in the rehabilitation department. Considering the patient’s non-obstructive urinary retention, there was no obvious history of neurological injury, and urodynamics suggested that the contraction of the urethral muscle was weak, presumably due to bladder muscle paralysis caused by the drug (654-2), or the onset of excessive urinary retention so that the bladder is extremely distended, and the urethral muscle stretches and leads to dysfunction of urinary evacuation. It was suggested that surgery should not be considered first, and the patient was given ultrashort wave (anti-inflammatory and swelling) and low-frequency pulse electrical stimulation (to promote the contraction of the bladder muscle), and at the same time, the patient was educated so that he could understand the principle of urination and the methods to promote urination. After 1 week of treatment, the patient had obvious feeling of bladder filling and desire to urinate, and the catheter was removed in the morning of the 10th day after emptying the morning urine. At noon, the good news came that the patient urinated once on his own, and the amount of urine was more, and the whole family cheered together, all of them sighed with relief; however, the urination in the afternoon was not as smooth as the previous one, and at night it was even less, and the catheterization was carried out again, and the physiotherapy was continued. Why could she not urinate on her own again? Her classmate said that every time her father went into the toilet, the whole family waited for the result outside, and the longer the time of urination, the more anxious the people inside and outside the toilet were. This may be due to the fact that the recovery of urinary function is still unstable and the mental stress is relatively high. Although catheterization is needed again, it gives the patient hope. Psychological counseling for the patient’s actual situation, continue physical therapy, 1 week after the catheter was removed again, urination returned to normal. The family was very thankful and the classmate regretted not thinking of me earlier. Patients with non-obstructive urinary difficulties like the father of the classmate, such as post-partum, major abdominal surgery, etc. caused by urinary retention, early treatment with appropriate physiotherapy can achieve better results.
