ObjectiveTo investigate the approach and application value of DJ-catheter indwelling in transurethral giant prostate enucleation.

MethodsSixty-four patients with giant prostatic hyperplasia were randomly divided into the catheter group and non-catheter group(32 cases in each group).The DJ-catheter was implanted, and applied to the giant prostate enuclator combined with crusher in the catheter group, while the non-catheter group were treated with the giant prostate enucleation combined with morcellator.The operative time, gland quality of excision, bladder irrigation time, indwelling time of urinary catheter, postoperative hospital stay, decreased hemoglobin(Hb), and international prostate symptom score(IPSS), quality of life index score(QOL), maximum urine flow rate(Qmax) and residual urine(PVR) after 6 months of surgery were compared between two groups.The ureteral injury situation, bladder mucosa damage, secondary bleeding and other complications in two groups were recorded.

ResultsThe operative time in catheter group was significantly longer than that in non-catheter group(P < 0.01).The differences of the amount of gland excision, bladder irrigation time, indwelling catheter time, postoperative hospital stay and Hb decreasing between two groups were not statistically significant(P>0.05).The differences of the prostate volume, IPSS score, QOL score, Qmax and PVR between two groups were not statistically significant after 6 months of surgery(P>0.05).The incidence rate of complications in catheter group was lower than that in non-catheter group(P < 0.05).

ConclusionsDJ-catheter is a simple, safe and effective auxiliary means to avoid damage to the ureteral opening and bladder triangle, and which can make the operation of transurethral giant prostate enucleation combined with morcellator more smooth, and the identification of ureteral orifice more clear and convenient.
