Partial (Morning and Evening) CIC for Patients with Partial Bladder Emptying Disorders

CIC is often used for patients with NB who cannot excrete enough urine [1]. By regularly inserting a disposable catheter into the urethra or bladder diversion four to six times a day to empty the urine, the bladder capacity is controlled within a safe capacity, and the bladder pressure is controlled within a safe pressure range, to avoid complications such as upper urinary tract dilation [2], ureteral reflux [3], hydronephrosis [4], and renal failure [2] caused by long-term high bladder pressure. Internationally, the use of CIC is recommended. As the preferred treatment method for patients who cannot fully and safely empty their bladder, especially for those with neurogenic voiding dysfunction, it is an effective measure to achieve urinary bladder control [5]. According to literature, the indications for CIC are very broad [6], but for patients who have not completely lost bladder voiding function, they can use partial or only morning and evening CIC (also called morning and evening CIC). These methods that do not have to rely entirely on CIC for urination are called partial CIC or timed CIC (selected time clean intermittent catheterization, STCIC) or morning and evening CIC (morning evening CIC, MECIC), or morning, noon, and evening CIC (morning evening noon CIC, MENCIC). The purpose of STCIC is to prevent and treat a series of complications caused by excessive PVR leading to high bladder pressure (enuresis, urinary incontinence, etc.), protect the kidneys, and improve the quality of life. With a limited number of catheterizations per day (two to three times), it can control abnormal voiding symptoms and reduce catheter-induced UTI.
