Effect of transurethral resection of the prostate on nocturia and sleep quality in men with benign prostatic hyperplasia

Objective To evaluate the effect of transurethral resection of the prostate on nocturia and sleep quality in men with benign prostatic hyperplasia. Methods This retrospective study included 122 patients who underwent TURP(transurethral resection of the prostate) for BPH(benign prostatic hyperplasia)from December 2016 to December 2018.The age was(69.7±7.9)years old. There was 20 cases with diabetes and 40 cases with hypertension. The preoperative mean prostate volume was (64.4±41.2)ml and mean BMI was (24.3±2.7)kg/m2. The preoperative IPSS score was (20.5±5.5) points, the number of nocturia events(assessed by the seventh question of IPSS) was (4.4±1.9) times, hours of undisturbed sleep (HUS) was (1.7±1.0) h, 110 cases with HUS 200 ml with nocturia (4.5±1.9) times, 9 cases had a maximum bladder capacity ≤200 ml with nocturia (4.7±1.7) times. All 122 patients were treated with TURP. Result 122 patients were followed up for 3-20 months. After operation the number of nocturia significantly decreased to (1.9±1.23) times (P 200 ml. The nocturia did not improve significantly after surgery (P>0.05) in the group with a maximum bladder volume ≤200 ml, and the nocturia in the group with a maximum bladder capacity >200 ml had significantly improvement (P 200 ml, and there was significant difference compared with before surgery (P<0.05). Conclusion TURP can significantly prolong the HUS of BPH patients with nocturia, and improve the life and sleep quality of patients. TURP partly reduces the number of nocturia, but some patients still suffer from nocturia after operation. The high total score of IPSS before operation and the maximum bladder volume ≤200 ml are the risk factors for nocturia after operation.
