Background of the study: Percutaneous nephrolithotomy (PCNL) is the gold standard treatment for kidney stones larger than 2 cm. PCNL has replaced open surgical removal of large or complex calculi at the most institutions. The success of PCNL is related to the ability to achieve an optimum access tract and proper fragmentation. A wide range of lithotripsy techniques are currently available. One of these is ultrasonic lithotripsy, in which the stones are fragmented and sucked out simultaneously. This technique induces minimal tissue injury and could be considered as a standard modality for PCNL. The pneumatic lithotripter uses pneumatic ballast, which crushes the stones without producing any thermal effects. Because this mechanical energy passes along the metal wire to the stone, the probe works like a chisel on the stone surface. This modality destroys all stones, regardless of their composition. There were very few studies had been done in this context in our country, so I had decided to do this study to compare the outcome of stone fragmentation with pneumatic and ultrasonic lithotripter during percutaneous nephrolithotomy. Objective: To compare the outcome of stone fragmentation with pneumatic and ultrasonic lithotripter during percutaneous nephrolithotomy. Materials & Methods: This Prospective Interventional Study (Quasi Experimental Trial) was performed in Department of Urology, National Institute of Kidney Diseases and Urology, Sher-E- Bangla Nagar, Dhaka during the period from December 2014 to May 2016. A total of 60 subjects will be selected with renal calculi (as per inclusion & exclusion criteria), among these, half of the patients will be group A (using pneumatic lithotripsy) & rest of the patients will be group B (using ultrasonic lithotripsy). The study subjects were underwent PCNL under general anesthesia, half of which used pneumatic lithotripter and rest used ultrasonic lithotripter for stone fragmentation. Above mentioned outcome variables were assessed both per-operative and post-operatively. Data were collected, processed & analyzed. Statistical analysis of relevant variables was done by unpaired Student’s T test and Chi Square test. P value Â0.05 was considered significant. Results: Total 60 patients were selected for study according to the selection criteria. Of the 60 subjects, 30 patients, those who were done PCNL by pneumatic lithotripsy were labeled as Group A and 30 patients, those who were done PCNL by ultrasonic lithotripsy, were labeled with Group B. Distribution of respondents in terms of different parameters is shown in tabulated form and statistical analysis was done in both groups to see statistical significance, p value less than 0.05 was considered significant. The mean stone fragmentation time was 27.23±4.78 (18-38) min in PCNL by pneumatic lithotripsy and those were 23.80±5.30 (13-34) min in by ultrasonic lithotripsy which is statistically significant. Other variables of interest which includes stone clearance rate, post operative haematuria and post operative hospital stay, were not statistically significant. Conclusion: Comparing the findings of the present study, results indicate that stone fragmentation time is lesser in ultrasonic lithotripsy than pneumatic lithotripsy in PCNL which decreases the overall operative time.

Objective: To determine the improvement of the quality of life in patient of BPH after transurethral resection of prostate. Methods: A total of 102 of patients complaining lower urinary tract symtoms due to Benign prostatic hyperplasia (BPH). Each of the patient was followed up at 8 weeks (1st visit), 16 weeks (2nd visit) and 24 weeks (3rd visit) after transurethral resection of prostate (TURP). Before TURP for base line study of each patient was evaluated by history, physical examination, digital rectal examination (DRE), International Prostate Symptoms Score (IPSS), Quality of Life Score (QOL), Urinalysis, volume of the prostate and post voidal residual urine (PVR) were determined by ultrasonogram. Improvement of lower urinary tract symptoms and quality of life was determined using IPSS. Improvement was based on the changes from base line in symptoms,urinary flow rate, amount of post voidal residual urine and quality of life.Urine flow rate was measured by uroflowmetry as peak urinary flow rate (Qmax), voiding time and voided volume and was considered valid only if the voided volume was >200 ml. Symptoms were assessed using IPSS & consisting of seven symptoms (frequency, nocturia, urge in continence, urgency, hesitancy, terminal dribbling and sense of incomplete evacuation) that were graded from 0-5. An overall symptoms score was calculated. Result: 102 cases were evaluated by history, physical examination, digital rectal examination (DRE), international prostate symptom scoring (IPSS), quality of life (QOL) scoring, uroflowmetry, post voided residual urine (PVR) and volume of prostate by USG and serum prostate specific antigen (PSA). Cases were selected between 60-75 years. In group-A, among 42 cases (41.2%) <65 years and group-B, 60 cases (58.80%) > 65 years. Age of the patients of each group was compared with IPSS, PVR, Qmax and QOL. Before TURP, IPSS range 17-25 and mean 21.61+2.43, after TURP, range 0-7 and mean 4.27+1.71). There was significant correlation between the IPSS obstructive scores and Qmax at base line (P=<0.001), while correlations at the 1st, 2nd and 3rd follow up significant. There was also a significant correlation between IPSS obstructive score and PVR, and quality of life. After TURP, the IPSS Score showed significant improvements in urinary symptoms with the IPSS showing more significant change for obstructive symptoms. A significant improvement of IPSS was found from 2 months to 6 months follow up after TURP. The change was tested using “paired student ‘t’ test”. Mean quality of life was 5.01+0.64 at base line, which became 0.60+0.91 at end point and therefore change of mean QOL was -4.41+0.93 ml. A significant improvement QOL after transurethral resection of the prostate. The change was test using ‘Paired Student‘t’ test’. The change was found significant (P=<0.001). Conclusion: Transurethral resection of prostate resolves obstructive symptoms, rapid improvement of urinary flow rate and quality of life that is why it is considered as gold standard treatment for moderate to severe symptomatic BPH patients.

Objectives: To review the outcomes of modification of groin lymph nodes dissection on morbidity from surgical treatment of a patient with penile cancer and to find out accurate treatment plan according to stages of the primary lesion from current literatures. Methods: We searched the pubmed database for English Language published in the past for years using incidence, etiology, pathology, clinical presentation, staging and management of penile cancer. Result: From retrieved literatures better understanding of pathologic features allow for stratification of patients into low, intermediate, or high risk for lymph node involvement. Lymphatic mapping to this stratification improves selection of patients who might benefit from lymph node dissection after excision of the primary lesion. The recent use of a modified lymph node dissection has minimized morbidity. Current chemotherapy agents are ineffective in this disease. Conclusion: Patholoigc features of the primary lesion and the incorporation of lymphatic mapping have improved the selection of patients who might benefit from lymph node dissection. The use of a modified lymph node dissection in selection patients has decreased morbidity. Effective chemotherapy agents are needed in the management of advanced penile cancer.

Objectives: To evaluate urinary symptoms and quality of life in patient with BPH before and after TURP. To determine the impact of TURP on the urinary symptoms (IPSS) and peak urinary flow rate. Methods: This study is prospective study carried out between 2010 and 2011 in the department of Urology, National Institute of Kidney Diseases & Urology. Total 102 cases were selected purposively according to selection criteria. Each patient was observed and followed up at 8 weeks (1st visit), 16 weeks (2nd visit) 24 weeks (3rd visit) after transurethral resection of prostate (TURP). IPSS score, QOL score also recorded and uroflowmetry was done to see the peak urinary flow rate (Qmax) of urine and voiding time. USG was done to see post voidal residual urine volume and DRE also done in selected cases. Data was complied and statistical analysis were done using computer based software, Statistical Package for Social Science (SPSS), using paired ‘t’ test. A P value <0.05 was taken as significance. Results: Before TURP, IPSS range 17-25 and mean 21.61+2.43, after TURP, range 0-7 and mean 4.27+1.71). Hence a significant improvement of IPSS was found from 2 months to 6 months follow up after TURP. The change was tested using “paired student ‘t’ test”. Before TURP Qmax range 7-12.2 and mean was 9.96+1.69, which became range 18-25 and mean was 22.61+2.28 after TURP and therefore change of mean Qmax was 12.64+2.69. The change was tested using “paired student ‘t’ test”. The change was found significant (P<0.001). Conclusion: Transurethral resection of prostate resolves obstructive symptoms, rapid improvement of urinary flow rate Bangladesh Journal of Urology, Vol. 16, No. 1, Jan 2013 p.11-15

Objectives: Evaluation of the international prostate symptom score(IPSS) and quality of life score before and following TURP in BPH patients and correlation with objective parameters(Qmax and PVR). Methods: This purposive clinical trial was carried out in the Department of Urology, Sir Salimullah Medical College and Mitford Hospital, Dhaka, from January 2008 to December 2008. Total fifty patients between 50-72 years attending for the treatment of BPH with LUTS were included for the study according to inclusion & exclusion Patients with carcinoma prostate riteria. Selected patients underwent transurethral resection of prostate. All of them had baseline IPSS, QoL score, Qmax, voided volume, voiding time and PVR. They were followed after 1 month and 3 months with same parameter and compared with the baseline values. Correlation of IPSS and QoL score was done with Qmax and PVR. Results: The baseline IPSS in this study was 25.18±1.45. At one month and three months follow up visits after TURP, the IPSS was decreased to 15.0±1.07 and 8.14±0.76 respectively. The mean QoL score was 5.30± 0.46 before TURP. After one month of TURP it was 3.20± 0.45 and after 3 months of TURP it was 1.86 ± 0.57. There was significant negative correlation between the QoL score and Qmax in the preoperative period (r = -0.606, p=0.001), at the 1st follow up visit after one month of TURP (r = -0.171, p=0.235) and at the 2nd follow visit after three months of TURP (r = -0.680, p =0.001). There was positive correlation between the QoL score and PVR in the preoperative period (r = 0.394, p=0.005), at the 1st follow up visit after one month of TURP (r = 0.047, p =0.748) and at the 2nd follow up visit after three months of TURP (r = 0.471, p=0.235). Conclusion: There was significant improvement of quality of after TURP and There was significant negative correlation between the QoL score and Qmax and positive correlation between the QoL score and PVR.
