Objective Benign prostatic hyperplasia (BPH) is one of the most common diseases found among elderly men. Even though multiple risk factors of BPH have been identified in the past, the risk factors which have a direct impact on prostate volume have not been identified. In this study, we aim to determine the most significant contributing risk factors to prostate volume enlargement by analyzing possible associated risk factors previously studied. Methods This is a quantitative study with an analytical observational design, performed using a retrospective cohort approach. Total sampling was performed on 83 patients who underwent transurethral resection of the prostate (TURP) in Sanglah General Hospital from January to February 2019. Bivariate analysis is performed to examine each variable's association with prostate volume followed by a multivariate analysis. All variables were reassessed with path analysis to measure the direct effects, indirect effects, and total effects on prostate volume. Results Bivariate analysis shows that serum testosterone (R=0.208; p =0.059) and prostate-specific antigen (PSA) level (R=0.626; p =0.001) have a significant association with prostate volume. Multivariate analysis shows that serum PSA (B=1.4; p =0.001; 95% confidence interval [95% CI]=1.039–1.770) and testosterone (B=0.024; p =0.005; 95% CI=0.008–0.041) levels are significant among all the analyzed risk factors. There is a significant and strong effect of PSA to prostate volume (c=0.636; p =0.001) whereas testosterone has a significant albeit weak effect to prostate volume (c=0.246; p =0.009) based on the total effect of the path analysis. Conclusion Serum testosterone and PSA levels are significantly associated with prostatic volume increase among BPH patients.
Objective: to know the predictive factors of inguinal lymph node metastasis in men with penile cancer. Methods: this was a retrospective study on 65 patients with penile cancer in Sanglah Hospital, Denpasar, Bali from 2011 to 2015. Patients were included in analysis if they had undergone partial or total penectomy, and inguinal lymph-node dissection or excisional biopsy. Inguinal lymph node metastasis was defined as tumor positive node based on histopathology finding in patients who underwent inguinal lymph node dissection or excisional biopsy. Data retrieved from this study was analyzed by Chi Square and Kruskal-Wallis test. Results: a total of 65 patients diagnosed as penile cancer in Sanglah Hospital, Denpasar, Bali from 2011 to 2015. Mean age of these patients was 53.24 ± 13.42 years. The youngest age was 27 years old and the oldest was 86 years old. Fifteen patients were excluded for different reasons, remaining 50 patients for further analysis. From 50 patients included in analysis, 25 patient (50%) had inguinal lymph node metastasis. There were significant correlation between pathologic stage of the primary tumor (p=0.021), histologic grade (p=0.020), and vascular invasion (p=0.008) with the presence of inguinal lymph node metastasis. Based on pathologic stage of the primary tumor, only 1 of 7 patients (14%) with pT1 had inguinal lymph node metastasis compared with 10 of 24 patients (42%) with pT2, 10 of 15 patients (67%) with pT3, and 4 of 4 patients with pT4 (100%). Based on histologic grade, only 2 of 9 patients (22%) with grade I had inguinal lymph node metastasis compared with 18 of 36 patients (50%) with grade II, and 5 of 5 patients (100%) with grade III. Based on vascular invasion, only 15 of 38 patients (39%) without vascular invasion had inguinal lymph node metastasis compared with 10 of 12 patients (83%) with vascular invasion. No significant correlation was found between age and the presence of inguinal lymph node metastasis (p=0.829). Conclusion: pathologic stage of the primary tumor, histologic grade, and vascular invasion were predictive factors of inguinal lymph node metastasis in men with penile cancer.
BACKGROUND: Urinary retention has many etiologies. One of them is urethral stricture or the narrowing of urethral lumen due to fibrotic tissue. Urethral stricture is considered a medical emergency condition because it might cause complications in some extent. At present, there are several surgical techniques introduced with their advantages and disadvantages. AIM: The study aimed to compare the outcome of minimal invasive therapy (MIT) or excision and primary anastomosis (EPA) techniques. METHODS: A retrospective cohort study was performed on patients with partial posterior urethral stricture. The inclusion criteria were all patients with partial posterior urethral stricture who underwent MIT or EPA from 2014 to 2018. The data of International Prostate Symptom Score (IPSS), quality of life (QoL), urinary peak flow rate (Qmax), urine residue, erection hardness score, clean intermittent catheterization (CIC), recurrence, and penile perception scores (PPS) were obtained and analyzed postoperatively. RESULTS: Thirty-four patients included in the study, consisted of 17 patients for each group. EPA group showed significantly superior to MIT in Qmax (p < 0.001), CIC (p = 0.007), and PPS score (p = 0.003). However, no significance differences were found in QoL (p = 0.071), IPSS score (p = 0.083), bladder urine residue (p = 0.688), recurrence (p = 0.225), and erectile function (p = 0.303). CONCLUSION: EPA may be superior to MIT in some aspect. However, other advantages of MIT could be outweighed EPA techniques, such as QoL, IPSS, bladder urine residual, stricture recurrence, and erectile function. MIT still has a place to be the first-line management of partial posterior urethral stricture.
