Which Factors Affect the Hospital Re-admission After Treatment Approaches to Urethral Strictures?

Objective: To investigate patient- and procedure-related factors associated with hospital re-admission following urethral manipulations for the\udtreatment of urethral strictures.\udMaterials and Methods: Data of patients who underwent dilation or internal urethrotomy for urethral strictures between 2011 and 2016 were\udretrospectively analyzed. Patients who were admitted to our institute for any reason within one month after hospital discharge were evaluated. The\udpatient- and procedure-related factors affecting the readmission rates were revealed by multiple binary logistic regression using stepwise backward\udelinimination.\udResults: The average age of 76 male patients was 61.7±14.4 years. The mean maximal flow rate at preoperative uroflowmetry was 6.01±4.3 and the\udmedian American Society of Anesthesiologists score was 2.38. The process was the first for 45 (59.2%) patients, the second for 16 (21.1%) patients,\udthe third for 9 (11.8%) patients, and the fourth for 6 (7.9%) patients. Amplatz dilators, cold knife and Ho:YAG laser were used in 50%, 27.6% and\ud22.4% of patients, respectively. The mean length of hospital stay was 0.89±0.31 days, and the complication rate was 19.7% (15/76). The mean\udurethral catheter dwell time was 8.9±14.2 day. Overall, the procedure was successful in 61 (80.3%) patients and failed (Qmax <15 mL/sec) in 19.7% of\udthe cases. Fifteen (19.7%) patients were re-admitted, while 2 (2.6%) patients among them were re-hospitalized for further treatment. Comorbidity\udand age were independent predictors of re-admission.\udConclusion: We found that younger age and lower comorbidities predicted hospital re-admission following procedures for urethral strictures
