RESUMO
【Objective】 To analyze the results, characteristics and clinical value of video urodynamic study (VUD) of lower urinary tract symptoms (LUTS) in young male. 【Methods】 A total of 106 young male LUTS patients (18-45 years old) who received VUD in our hospital during Jan.2016 and Sep.2021 were collected to analyze the clinical and imaging urodynamic characteristics. 【Results】 Of the 106 patients, 55 (52.44%) had neurogenic lower urinary tract dysfunction (NLUTD)with clear neurological etiology, and 51 (48%) had non-neurogenic lower urinary tract dysfunction (NNLUTD). In NLUTD patients, dysuria was the most common symptom (76.74%); lumbosacral lesions were the main cause (76.36%); imaging urodynamics indicated weakening of detrusor muscle in different degrees. In NNLUTD patients,the main symptoms were frequent urination (48.72%) and dysuria (48.72%); about 58.97% of patients had two or more LUTS, and the main diagnosis was detrusor underactivity (DU)(35.90%). 【Conclusion】 NLUTD in young male is characterized by varying degrees of detrusor muscle weakness, detrusor sphincter dyscoordination, and decreased bladder compliance. NNLUTD is mostly caused by detrusor overactivity (DO) and DU.
