Longitudinal changes of several parameters in patients with preoperative LUTS.
Fig 1.
Changes from the baseline values in the International Prostate Symptom Score (IPSS) and quality of life (QOL) index in patients with and without lower urinary tract symptoms (LUTS) evaluated before robot-assisted laparoscopic radical prostatectomy.
A) Total IPSS score. B) Voiding symptom score. C) Storage symptom score. D) QOL index. The voiding symptom score is the sum of the intermittency score, weak stream score, and straining score of the IPSS; the storage symptom score is the sum of the frequency score, urgency score, and nocturia score of the IPSS.
Fig 2.
The scatter plots of the urine output rate versus the voided volume at each voiding in the patients with and without lower urinary tract symptoms (LUTS) before robot-assisted laparoscopic radical prostatectomy (RARP).
Blue diamond plots and the blue regression line indicate the micturitions of the patients with preoperative LUTS. The coefficient of determination is 0.05. Red square plots and the red regression line indicate the micturitions of the patients without preoperative LUTS. The coefficient of determination is 0.24. The vesical adaptation response to diuresis is seen in patients without preoperative LUTS.
Fig 3.
The scatter plots of the urine output rate versus the voided volume at each voiding.
A) Micturition plots of the patients with preoperative LUTS stratified by evaluation time period. Blue diamond plots and the blue regression line indicate the micturitions before RARP. The coefficient of determination is 0.05. Orange square plots and the orange regression line indicate the micturitions 3 months after RARP. The coefficient of determination is 0.22. Gray triangle plots and the gray regression line indicate the micturitions 12 months after RARP. The coefficient of determination is 0.23. * indicates significant differences of the coefficient of correlation before RARP after Bonferroni adjustment. B) Micturition plots of the patients without preoperative LUTS stratified by evaluation time period. Blue diamond plots and the blue regression line indicate the micturitions before RARP. The coefficient of determination is 0.24. Orange square plots and the orange regression line indicate the micturitions 3 months after RARP. The coefficient of determination is 0.25. Gray triangle plots and the gray regression line indicate the micturitions 12 months after RARP. The coefficient of determination is 0.33.
