Objective: To define the relationship between intravesical prostatic protrusion (IPP), prostate specific antigen (PSA), and prostate volume (PV), and to determine which one is the best predictor of bladder outlet obstruction (BOO) due to benign prostatic enlargement. Material & method: 95 male patients > 40 years old presenting with LUTS and BPH, between January until July 2012. They were evaluated with digital rectal examination (DRE), International Prostate Symptoms Score (IPSS), total PSA serum, uroflowmetry, post-void residual urine measurement, IPP and PV using transabdominal ultrasound. Statistical analysis included Chi-square and Spearman’s Rank correlation test.Receiver Operator Characteristic (ROC) curves were used to evaluate the correlation of PSA, PV, and IPP with BOO. Results: Mean PSA was significantly higher in obstructed patients (8.6 ng/mL; 0.76-130) compared to non-obstructed patients (6.44 ng/mL; 1.0-40.6). Mean PV was significantly larger in obstructed patients (50.33 mL ± 24.34) compared to non-obstructed patients (45.39 mL ± 23.43). Mean IPP was significantly greater in obstructed patients (7.29 ± 2.78) compared to non-obstructed patients (6.59 ± 2.93). The Spearman rho correlation coefficients were 0.617, 0.721, and 0.797, for PSA, PV, and IPP, respectively. Using ROC curves, the areas under the curve for PSA, PV, and IPP were 0.509, 0.562 and 0.602, respectively. The positive predictive values of PV, PSA, and IPP were 59.7%, 55.6% and 60.2% respectively. Conclusion: PSA, PV, and IPP measured through transabdominal ultrasonography are noninvasive and accessible method that significantly correlates with BOO in BPH patients. IPP is a better predictor for BOO than PSA or PV.Keywords: Bladder outlet obstruction, intravesical prostatic protrusion, prostate specific antigen, prostate volume, transabdominal ultrasound, benign prostate hyperplasia.
Objective: This study aimed to find out the effectiveness of percutaneous nephrostomy (PCN) as palliative decompression of the obstructed urinary system. Materials & Methods: A case control study was performed with 118 patients (69 female and 49 male) with obstructive uropathy who were undergoing PCN during 2009 until 2012, retrospectively. The mean of age was 50.03 years. The PCN technique involves an ultrasound-guided puncture of the dilated collecting system with nephrostomy trocar than insert an 8 Fr nasogastric tube as nephrostomy catheter. Differences of renal function between benign and malignancy were assessed using Independent t-test. Changes in renal function after procedure were expressed as mean ± SD and analyzed using Pair t-test. Results: There was no procedure-related mortality. The most cause of malignancy was cervix cancer (36.4%) while the result of a benign process was 28.8% of urinary tract stones. Dialysis before procedure were performed in 43 (36.4%) consisting of 42 malignancies and 1 benign process. Improvement in renal function were statistically significant both benign and malignant groups seen in the levels of creatinine and blood urea nitrogen (BUN) before and after procedure (p<0.001). The mean differences were also statistically significant at the preoperative creatinine values between benign and malignant processes (p=0.019) but BUN levels before and after as well as postoperative creatinine levels showed no significant difference. Conclusion: PCN is a widely used technique, with a high technical success rate and low rate of complications. Obstructive uropathy due to benign processes had a better prognosis than malignancy after PCN treatment. Hemodialysis was mainly performed in patients with malignancy prior to PCN.
Objective: To assess the effectiveness of Percutaneous Nephrolithotomy (PCNL) at age > 65 years and its complication. Material & method: Fifty-four patients with renal and proximal ureteral stones who underwent PCNL with ultrasound techniques combined with X-Ray at Sardjito and Pantirapih hospital, during 2007 to 2012. Laboratory data is in the form of hemoglobin, leukocyte count, trombocyte, haematocrit, natrium, potassium, chloride, BUN, creatinine both pre-operative and post-operative. The samples were divided according to age < 65 years old and above. In analyzing categorical data, we used chi-square test, whereas the numeric data analysis is using independent t-test with p < 0.05. Results: We found no significant differences between the age groups < 65 years and age > 65 years in stone location, presence of hydronephrosis, its grade and location. There also no difference based on operative time, intra-operative procedure, its complication and the day of DJ stents removal and nephrostomy. Both group showed similar result on laboratory findings. However, we found that the older age group have 2 days longer in the length of hospitalization than the younger age groups (p = 0.05) and history of diabetes mellitus and hypertension with p < 0.05. Conclusion: PCNL is a safe and effective procedure with minimal complications for the treatment of kidney and proximal ureteral stone, even for patients with co-morbidity. PCNL technique with guidance of ultrasound for early access would help tomake the operating time shorter and less exposure to ionizing radiation.Keywords: Percutaneous nephrolithotomy, age > 65 years old, effectiveness, safety.
Background:Early detection of prostate cancer is a possible means of decreasing the mortality and increasing the quality of life. Objective :To determine whether the prostate specific antigen (PSA), abnormal DRE, family history, age, and prostate volume could increase the specificity and sensitivity of screening for prostate cancer. Methods :We included 92 patients with PSA > 4 ng/ml between January and December 2011 in Sardjito Hospital. Patients received prostate biopsy due to having abnormal serum prostate specific antigen (PSA) level. The relationship between the possibility of prostate cancer and the following variables were evaluated including: age; PSA level, prostate volume, DRE finding and family history. By using chi-square analysis, multiple logistic regression and receiver operating characteristic (ROC) curve were drawn based on the predictive scoring equation to predict the possibility of prostate cancer. All analyses were performed with SPSS, version 18.0. Results:We analyzed 92 patients with PSA > 4 ng/ml. It showed the relationship between the possibility of prostate cancer and the following variables, including : age (p < 0.001), PSA level (p < 0,001), DRE finding (p < 0.001) family history (p < 0,001) except prostate volume (p = 0.398). Using a predictive equation, P = 1/(1-e-X), where X= -3,821 +1.846 (if DRE positive) + 2,488 ( if family history positive ) + 1.718 ( when PSA > 10 ) + 1.414 ( when age > 68), followed by receiver-operating characteristic curve analysis, it showed the sensitivity 90,4% and specificity 85 % in predicting the possibility of prostate cancer. Conclusion: Age, DRE finding, PSA and family history are factors associated prostate cancer. They can be used as independent predictor to predict prostate cancer. Key words: Logistic regression, early detection,prostate cancer
Objective:To find out effectiveness of percutaneous nephrostomy (PCN) and patient survival rate as palliative decompression of the obstructed urinary system due to malignancy (urogenital neoplasias). Materials & Methods: A cohort retrospective study was performed with 76 patients (58 female and 18 male) with malignancy process who were undergoing percutaneous nephrostomy during January 2009 – December 2012, in Sardjito General Hospital Yogyakarta. Survival analysis was done by Kaplan-Meier method and differences were assessed using the log-rank test. Results:There was no procedure-related mortality. The mean of age was 49.14 years. The primary tumoral site was the uterine cervix in 56.6 %, the bladder in 17.1 %, the prostate in 2.6% and other sites (intestinal, ovarium and other malignancies caused obstructive uropathy) in 23.7%. The patients died during the hospitalization period due to advanced neoplasia are 17.1%. The mortality rate was higher in patients with interval between diagnose of obstructive uropathy and nephrostomy > 7 days (HR=5.7; 95%CI 4.5-6.9; p = 0.001) and in those who required hemodialysis before the procedure (HR=6.1; 95%CI 4.7-7.4; p = 0.001). The survival rate was 55.2% (42/76) at 6 months and 32.9% (25/76) at 12 months. The percentage of the lifetime spent in hospitalization was 17.1% (13/76). There are no differences on survival rate in that patients based on neoplasias type and age.Conclusion: The urinary obstruction must be immediately relieved. The percutaneous nephrostomy is a safe and effective method for relief the obstruction. Patient with hemodialysis before the procedure had a poor prognosis.
