Intravesical prostatic protrusion (IPP) is a noninvasive parameter that can predict disease progression and development of complications in benign prostatic hyperplasia (BPH). This study was to determine the relationship between IPP and the presence of complications in BPH patients.
This was a cross-sectional study of BPH patients at Enugu State University of Science and Technology Teaching Hospital, Enugu. Patients were assessed for acute urinary retention (AUR), chronic urinary retention (CUR), epididymoorchitis, hematuria, hernia, urinary tract infection (UTI), serum creatinine, and prostate-specific antigen (PSA). They also had abdominal ultrasonography assessments for IPP, total prostate volume, bladder wall thickness (BWT), postvoid residual (PVR), hydronephrosis, bladder diverticulum, and urolithiasis using Sonoscape S11 with an abdominal-probe frequency of 3.5 MHz. IPP was measured in millimeter and divided into <10 mm and ≥10 mm. Data were analyzed using SPSS version 21 and were subjected to 1-way analysis of variance, chi-square test, and Pearson correlation. The odds ratios of development of complications at an IPP cutoff of 10 mm were calculated. P < .05 was considered significant.
A total of 118 patients with a mean age of 64.18 ± 10.96 years and a mean IPP of 14.29 ± 10.20 mm were included. Forty-eight patients had IPP < 10 mm and seventy patients ≥10 mm. Patients with IPP ≥10 mm had significantly higher mean BWT, International Prostate Symptom Score (IPSS), PSA, and PVR (P ≤ .05) and significantly more AUR, CUR, hematuria, hydronephrosis, and UTI (P ≤ .01).
Patients with IPP ≥ 10 mm have a significantly higher incidence of some complications.
膀胱内前列腺突出（IPP）是一个非侵入性参数，可以预测良性前列腺增生（BPH）的疾病进展和并发症的发展。本研究旨在确定 IPP 与 BPH 患者并发症之间的关系。
这是一项在埃努古州立科技大学教学医院进行的 BPH 患者的横断面研究。对急性尿潴留（AUR）、慢性尿潴留（CUR）、附睾炎睾丸炎、血尿、疝气、尿路感染（UTI）、血清肌酐和前列腺特异性抗原（PSA）等并发症进行评估。还使用 Sonoscape S11 对 IPP、前列腺总体积、膀胱壁厚度（BWT）、剩余尿量（PVR）、肾积水、膀胱憩室和尿路结石进行了腹部超声检查，探头频率为 3.5MHz。IPP 以毫米为单位进行测量，并分为<10mm 和≥10mm。使用 SPSS 版本 21 对数据进行分析，并进行单因素方差分析、卡方检验和 Pearson 相关性分析。计算 IPP 截点为 10mm 时并发症发生的优势比。P<0.05 被认为具有统计学意义。
共纳入 118 例患者，平均年龄为 64.18±10.96 岁，平均 IPP 为 14.29±10.20mm。48 例患者的 IPP<10mm，70 例患者的 IPP≥10mm。IPP≥10mm 的患者 BWT、国际前列腺症状评分（IPSS）、PSA 和 PVR 均显著较高（P≤0.05），AUR、CUR、血尿、肾积水和 UTI 发生率显著较高（P≤0.01）。
IPP≥10mm 的患者发生某些并发症的发生率显著较高。
