CIC Can Be Widely Applied Clinically

CIC can effectively solve the problem of safe urine discharge, prevent VUR and kidney damage, prevent complications of bladder emptying disorders (increased PVR and UTI), and reduce symptoms of urinary incontinence, frequency, and urgency, thereby improving quality of life. CIC is commonly used in patients with difficulty urinating and significant increase in PVR and is one of the effective treatments for difficulty urinating, increased PVR, and overflow incontinence [1, 2]. The causes of overflow incontinence are often due to weak detrusor contraction and lack of detrusor reflex, and the etiology may be the damage of nerve that controls the voiding reflex, bladder outlet obstruction (BOO), or the influence of certain drugs. If there is still a large amount of PVR after the obstruction, drugs and other causes are removed, or when the detrusor contraction force is significantly damaged and cannot be recovered, long-term CIC can be considered. CIC is also often used as a treatment for urinary retention after bladder augmentation (or autologous bladder augmentation and intestinal bladder augmentation), which can effectively prevent urinary system infections and protect upper urinary tract function [3, 4]. With a deeper understanding of CIC, total bladder resection plus controllable bladder surgery has become popular and recognized; CIC has also become the best way to empty the bladder for controllable urinary diversion. Therefore, if there is a bladder emptying disorder (increased PVR) and the catheter can be inserted into the bladder through the urethra or bladder outlet, CIC can be implemented. Therefore, CIC has a wide range of clinical application value. However, if CIC is used improperly, there is also a risk of complications such as UTI. Therefore, the indications for CIC need to be strictly mastered [5].
