INTRODUCTION: Laser therapy has gained increasing acceptance as a relatively less invasive treatment for lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH). From the early procedure of interstitial laser coagulation through to the use of holmium laser enucleation of the prostate, there has been an expanding body of evidence on the efficacy of such procedures. One of the newer lasers is the Green Light HPS 180 W laser. Studies with this GreenLight laser (GLL) (American Medical Systems, Inc, Minnetonka, MN, USA) showing results as good as those of transurethral resection of the prostate (TURP). In this paper, the efficacy of the new GLL 180-W versus the gold standard TURP in patients with LUTS due to BPH was tested in a prospective clinical trial. OBJECTIVE: To compare results of Green light laser (GLL) evaporisation of the prostatae and transurethral resection of the prostate (TURP) for treatment of BPH. MATERIJALS AND METHODS: A total of 62 patients with BPH were randomly assigned to two equal groups: TURP or GLL. RESULTS: Both groups were compared regarding all relevant preoperative, operative, and postoperative parameters. Functional results in terms of improvement of International Prostate Symptom Score (IPSS), maximum flow rate (Qmax), and postvoid residual (PVR) urine were assessed at 1, 3, 6 and 12 mo. A total of 62 patients completed 12 mo of follow-up in the TURP and GLL groups, respectively. Baseline characteristics were comparable. Mean operative time was significantly shorter for TURP. Compared to preoperative values, there was significant reduction in hemoglobin levels at the end of TURP only. A significant difference in favor of GLL was achieved regarding the duration of catheterization and hospital stay. In the GLL, no major intraoperative complications were recorded and none of the patients required blood transfusion. Among TURP patients, 6 required transfusion, 1 developed TUR syndrome, and capsule perforation was observed in 5 patients. There was dramatic improvement in Qmax, IPSS, and GLL compared with preoperative values and the degree of improvement was comparable in both groups at all time points of follow-up. Four TURP patients and one GLL patients developed bladder neck contracture treated by bladder neck incision; none in either group experienced urethral stricture or urinary incontinence. CONCLUSIONS: Compared to transurethral resection of the prostate, GreenLight HPS 180-W laser photoselective vaporization of the prostate is safe and effective in the treatment of patients suffering from lower urinary tract symptoms due to benign prostatic hyperplasia.

OBJECTIVE: The aim of the study was to analyzed the efficacy and safety of a minimally invasive surgical procedure using the Trans- Obturator-Tape with "outside-in" approach for treatment female stress urinary incontinence. PATIENTS AND METHODS: 171 women with stress urinary incontinence (SUI) associated with urethral hypermobility, underwent the T.O.T. procedure (March 2010 to January 2014). 27 patients were previously operated for incontinence. Mean age was 59 years (37-80). 6 patients were having mixed incontinence, and 51 had SUI with urgencies. A non-elastic, polypropylene tape was placed under the mid-urethra. The surgical placement technique utilises a trans-obturator percutaneous approach. All patients underwent post-operative clinical examination, cough-stress test (full bladder), uroflowmetry, and post-voiding residual assessment. RESULTS: Mean follow-up was 22 months (4-45). At 12 months follow-up 91,2% of the patients were completely cured. The overall peri-operative complication rate was 6.4% with no vascular, nerve or bowel injury. 5 patients (2.9%) had post-operative urinary retention. CONCLUSION: The present study confirms the results obtained by the instigator of the technique, E. Delorme, and allows us to consider T.O.T. as an effective and safe technique for the treatment of female stress urinary incontinence.

PURPOSE: To determine the factors that can improve the prediction of biochemical recurrence after radical prostatectomy for the patients with prostate adenocarcinoma. METHODS: Our study included 182 patients with prostate adenocarcinoma who were biopsied and underwent radical surgical treatment at the Clinic of Urology, Clinical Center of Serbia, Medical Faculty in Belgrade from 1994 to 2004. Patients were prospectively followed-up and monitored for a minimum of 8 years and data were statistically processed by multivariate regression analysis. We arranged the predictors into 3 regressive models. In the first model the predictors were clinical stage of the disease, preoperative Gleason score, F/T PSA ratio and PSA. In the second model these predictors were accompanied with the number of positive biopsies and percent of positive prostate biopsies. In the third model, patient follow-up was added to the predictors. In all 3 models biochemical recurrence was considered as a dependent variable. RESULTS: On multivariate analysis, patient follow-up (p<0.0001), percent of positive prostate biopsies (p<0.0001), bioptic Gleason score (p<0.0001) and preoperative PSA (p<0.003) were significant independent predictors of biochemical recurrence. The most successful prediction of recurrence that provided accurate prognosis for 80% of the patients was obtained by the third model using the percent of positive prostate biopsies, PSA and patient follow-up. CONCLUSION: As stated in multivariate analysis, the independent predictors according to the significance are the follows: patient follow-up, percent of positive prostate biopsies, bioptic Gleason score and preoperative PSA, whereas preoperative F/T PSA ratio is dependent predictor. The number of positive biopsies and clinical stage of the disease are of no significance.

UNLABELLED: Ileal conduit as a form supravesical derivaton, is still one of most popular method of urinary diversion, in daily urological practice. Bearing in mind this fact, this type of diversion, rightfully so, is also called the "gold standard" in the derivation of urine. Considering the fact of unnatural route of elimination of urine from the upper urinary tract that occurs during creation of ileal conduit, it is reasonable to expect that, in time, this type of diversion lead to some degree of renal insufficiency. Some authors, this effect on renal function, attribute to specific type of ureterointestinal anastomosis during formation of ileal conduit. A very important part of the surgical technique of creating ileal conduit is precisely a step of implantation ureters into the intestinal segment. The ultimate goal is to enable a more natural way of evacuation of urine from the upper urinary tract in terms of maintaining the quality of renal function. Numerous authors describes a quite number of techniques of ureteral implantation into the intestinal segment (Wallace A, Wallace B, Nesbit-Bricker, Le Duc ...). Each of these techniques has its own strengths and weaknesses, and the decision witch technique will be applied is still in the hand of urologist--operator, individually.Bearing in mind the fact of unnatural route of elimination of urine from the upper urinary tract that occurs during creation of ileal conduit, it is reasonable to expect that the renal function over the time will start to show signs of incipient or advanced failure. OBJECTIVE: To determine the most appropriate type ureterointestinal anastomosis in forming ileal conduit, as a form of supravesical urinary diversion, to ensure adequate renal function postoperatively as an important parameter of quality of life. METHODS AND PATIENTS: This is a retrospective study, which covered a population of 193 patients treated at the Department of Urology, Clinical Center of Serbia, who underwent creation of ileal conduit as a form of urinary diversion. The study was conducted 2007-2011. Postoperative follow-up lasts up to 48 months. The assess of the level of renal insufficiency were analyzed by monitoring parameters which determine the degree of anemia, and biochemical parameters of renal function. We have investigated three techniques of insertion of the ureters into the ileal conduit, which are used in the daily practice (Wallace A, Wallace B, Nesbit-Bricker). CONCLUSION: Kidney failure occurs equally often in all patients who underwent urinary diversion by ileal conduit, ignoring the type of insertion of the ureters to the intestinal segment.

INTRODUCTION: The majority of diverticular bladder tumors (DBT) are urothelial. Due to the lack of the muscular layer in the diverticulum, the progression of these tumors is easier than in the bladder wall. CASE REPORT: The case of invasive DBT with painless hematuria is presented. The patient was treated with diverticulectomy. CONCLUSION: Unifocal Stage-T3 DBTs can be successfully treated with diverticulectomy.

UNLABELLED: Substitution of the bladder with segment of the digestive tract, within the radical treatment of bladder cancer, as well as treatment of the other bladder abnormality, is extremely demanding surgical procedure, that aims adequate treatment of the underlying disease and provide patient's renal function within physiological level. Surgical implantation of the ureter into the intestinal segment are an important part of the surgical technique, the formation of ileal conduit, with the ultimate aim of providing a more natural way of evacuation of urine from the upper urinary tract in terms of maintaining the adequate quality of renal function. Which of the existing surgical method of implantation of ureter in the intestinal segment will be applied, it is for urologist to decided, according to his affinity and/or his operating school of origin. The literature describes many procedures of this technique (Wallace A, B Wallace, Nesbit-Bricker, Le Duc). Bearing in mind that the ileal conduit, as a form of supravesical derivation, is still one of most widely used method of urinary diversion, with a very large number of patients during the follow-up period were recorded certain complications of renal function disorders, which by some authors attributed to a type of ureterointestinal anastomoses, during the creation of ileal conduit. Having in mind the fact of unnatural route of elimination of urine from the upper urinary tract that occurs during creation of ileal conduit, it is reasonable to expect some degree of renal deterioration. These complications require prompt resolution. Bearing in mind the fact of unnatural route of elimination of urine from the upper urinary tract that occurs during creation of ileal conduit, it is reasonable to expect that the renal function over the time will start to show signs of incipient or advanced failure. OBJECTIVE: The main objective is to show the degree of renal deterioration, postoperatively, according to the type of insertion of the ureters to the ileal conduit. METHODS AND PATIENTS: The study was conducted retrospectively on material of Urological Clinic, Clinical Center of Serbia and on material of Faculty of Medicine, University of Belgrade, on 193 patients, for a period of five years (2007 to 2011), with a time of postoperative follow-up of patients up to 48 months (four years). Assessment of the level of renal deteriorisation was performed by ultrasound examination during regular audits of patients during follow-up. CONCLUSION: It was found that all three examed techniques in an insertion of ureter into ileal conduit were equally satisfactorily, with the similar degree of postoperative complications. Based on these facts, we can conclude, that the quality of life of patients in all three analyzed groups of ureteral insertion in the ileal conduit, approximately the same.

OBJECTIVE: to present relatively uncommon surgical procedure for the treatment of localized prostate cancer. MATERIAL AND METHODS: Six patients with localized prostate cancer (PCa) underwent perineal radical prostatectomy (PRP) from 2006 to 2010. The average age was 65 +/- 5.2 years. The average preoperative PSA was 7.8 +/- 1.3 ng/ml. Two patients had pT2b stage, while four had pT2c stage. Gleason score ranged from 4-7. RESULTS: All patients had negative surgical margins. Average operative time was 109 +/- 20 minutes and average blood loss was 525 +/- 180 ml. The urethral catheter was removed after 12 days in all patients except one, who required prolonged catheterization due to urinary fistula. All patients were continent after three months. Average postoperative PSA was 0.07 +/- 0.03 ng/ml. CONCLUSION: Perineal radical prostatectomy is valuable surgical procedure that provides good oncological results as well as urinary and sexual function.

OBJECTIVE: To examine the possible reasons for great varieties in urethral prostate specific antigen (urPSA) levels, in patients after radical prostatectomy (RP). MATERIALS AND METHODS: In 46 patients with pros-tate cancer, PSA, urPSA, total testosterone, body-mass index (BMI) and the stage of androgenic alopecia (AGA) were determined. Forty-five patients underwent retropubic RP, while one underwent cystoprostatectomy with orthotopic bladder construction, due to bladder cancer. RESULTS: Average patients age prior to surgery plus or minus standard deviation was 65.2 +/- 5.8 years. Average urPSA was 20.9 +/- 47.5 ng/ml (0.05 to 212 ng/ml, median 2.24 ng/ml). With urethral PSA cut-off of 2.0 ng/ml, two groups were formed: A (urPSA < 2.0 ng/ml) and B (urPSA = 2.0 ng/ml). Patients in the group A had significantly lower average AGA score, than the patients from the group B (2.4 +/- 1.3 vs. 4.4 +/- 2.2, p = 0.0003). In addition, patients from the group A had significantly lower pos-toperative PSA (0.07+0.08 ng/ml vs. 0.14 +/- 0.06 ng/ml, p = 0.0014). CONCLUSIONS: The patients with higher urPSA have higher AGA scores and higher postoperative PSA. This phenomenon is probably the consequence of higher local dihydrotestosterone activity in the scalp and PSA-secreting urethral glands.

OBJECTIVES: To estimate the ratio between urinary prostate specific antigen (uPSA) and tumor volume after prostate biopsy. METHODS: From 2000 to July 2008, uPSA concentration was determined in 60 patients with clinically organ-confined prostate cancer (PCa). All patients underwent six-area transrectal ultrasound (TRUS)--guided biopsy, with at least 12 biopsy cores. Single pathologist determined tumor grade (G), Gleason score (GS), the percentage of tumor infiltration (% TI) and the percentage of positive cores (% PC) in all biopsy cores. Additionally, relative tumor-biopsy volume (RTV) was calculated by multiplying % PC, % TI and prostate ultrasound-derived volume (Vol). Forty-one patients underwent retropubic radical prostatectomy (RRP), while 19 patients underwent radiation therapy. RESULTS: Average uPSA was 308.6 +/- 311.9 ng/ml (range 0.06-988 ng/ml), average PSA was 9.7 +/- 5.5 ng/ml (range 1.2-24.3 ng/ml), tumor grade 1.7 +/- 0.8, Gleason score 5.2 +/- 1.3, the percentage of tumor infiltration 27.6 +/- 21.8%, and the percentage of positive cores, 52.2 +/- 30.7%. Average RTV was 6.3 +/- 8.4 ml (0.29-56 ml). All patients were divided in two groups: I, with RTV 4 ml and II, with RTV = 4 ml. The patients with RTV 4 ml had lower G (1.4 +/- 0.6 vs. 2.1 +/- 0.8, p = 0.0002), lower GS (4.5 +/- 1 vs. 5.8 +/- 1.3, p = 0.003) and higher uPSA (389.4 +/- 340.8 vs. 193.1 +/- 229.7, p = 0.014). There were no differences in serum PSA levels between the groups. CONCLUSION: Relative tumor-biopsy volume (RTV) is useful parameter in the preoperative assessment of tumor volume. Patients with higher RTV had significantly higher G and GS. However, these patients had significantly lower uPSA. This phenomenon could be the consequence of compromised PSA drainage from the peripheral zone of the prostate, caused by the tumor.

A case of an adenocarcinoma within a horseshoe kidney (HK) is presented. Male patient presented with a history of a painless hematuria. A contrast enhanced magnetic resonance (MR) scan showed a horseshoe kidney. A large soft tissue mass was also noted on the right side. Kidney was receiving supply from two arteries on the left side and one at the right side. Angiography of the right renal artery demonstrated hypervascular tumor staining. The kidney was approached through midline abdominal incision, and a right heminephrectomy was performed. The histopathology examination showed pT2, grade 2 renal cell carcinoma. To conclude, angiography is indispensable for guiding surgical interventions.

UNLABELLED: Aim of our study is to analyze sensitivity and specificity of imaging procedures in characterization upper urothelial malignancies, according to algorithm suggested by American Urology Association. MATERIAL AND METHODS: We analyzed 242 patients with kidney tumor masses who had been operated during 2006/2007 at Urological clinic in Belgrade. Due to pathohistological exam 210 patients had kidney parenchyma and 32 patients upper urothelial kidney tumor. RESULTS: According to tumor stage, computed tomography was sufficient and definitive diagnostic tool concerning both renal epithelial and upper urothelial malignancy. Only in four cases 1.60% (4/242; CT in 3/4, MRI 1/4) preoperative site of origin was different from histopathology findings. This mislead to inappropriate surgery plan. CONCLUSION: Familiarity with limitations and capabilities of imaging modalities is crucial for appropriate diagnosis. It should respect algorithm but has to be individual adapted.

INTRODUCTION: Prolonged survival of patients undergoing radical cystectomy due to the infiltrative carcinoma of the urinary bladder has increased the need for development of the orthotopic bladder enabling preservation of the upper urinary ways for the extended period of time. Orthotopic bladder with tubular afferent segments in which ureters are implanted without antireflux mechanism has been introduced into the practice in 1984 by Studer and collaborates. MATERIAL AND METHODS: In the period 1998-2007 12 patients averagely aged 62 years were subjected to orthotopic derivation from ileum, when low-pressure reservoir was constructed and the ureters were implanted into the afferent non detubularized segment of ileum without antireflux mechanism. The follow-ups included determination of serum creatinine level, ultrasound monitoring of the upper urinary ways condition in three-month intervals and pyeloureterography with intravenously applied contrast medium one year after the surgery. Immediately before the follow-up examinations, the patients were asked to complete voiding and incontinence onset diary. RESULTS: Complete exclusion of the kidney that was in the stasis before surgery was evidenced only in one case, in a patient with tumor infiltration of the ureteral orifice. Significant obstruction of the uretero-ileal anastomosis was found in 4 renal units and it was resolved by antegrade balloon catheter dilatation. Diurnal continence was established in all patients within the initial 6 months after the surgery. Mild form of nocturnal incontinence persisted in 33% of the patients. Stenosis of the urethrovesical anastomosis was a cause of urine retention in 1.8% of patients and it was endoscopically resolved. CONCLUSION: The advantage of implantation into the afferent non detubularized segment of ileum over the antireflux mechanism has been verified in our study based on the low percent of stenoses.

OBJECTIVE: To analyze the outcome of orthotopic ileal neobladder related to complications and quality of life. PATIENTS AND METHODS: From 1985 to 2006, 75 patients with mean age of 57 years, (41-75) underwent radical cystectomy and orthotopic ileal neobladder substitution. The mean follow up was 72 months (6-144). Mean operative time was 240 minutes. RESULTS: Intraoperative blood loss ranged from 250 to 2810 ml. Ureteral stents were removed on 14th postoperative day, and patients were discharged at 2st day, average. Complications appeared in 23 patients. There were two recurrent TCC in the neobladder. Three patients died from pulmonary embolism. Vesicoureteral reflux appeared in three patients, and it was bilateral in two patients. Total of 98% patients have daytime continence. CONCLUSION: Continent urinary reservoirs represent the state of the art in urinary diversion. Surgeons who perform these operations are urgent to institute requirements for careful long-term follow-up of these patients.

The current referential literature describes over 40 surgical techniques of continent urinary derivations. A variation of ureterosigmoidostomy, published by Hadzi Djokic et al. (1996) is a combination of the original Mainz pouch II (sigma rectum pouch) technique (Fish & Hohenfellner, 1991) and modified ureterointestinal anastomosis as described by Camey & LeDuc (1979) with a few new details described by the author himself. In the period 1994-2006, the total of 236 patients were treated by this method. Radical cystectomy in cases of multifocal transitional cell carcinoma of the bladder was the most common indication for this method (91,5%). In the course of follow-up (mean duration 24 months) the quality of life (QL) of these patients was evaluated by physical characteristics, mental status, social aspects and comparative evaluation of quality of life with ileal conduit which is still considered the "gold standard" for urinary derivations. A very good quality of life in all studied dimensions (3/4) patients) suggests the fact that this form of continent urinary derivation provides the patients with the fair quality of life and confirms justifiability of this surgical procedure under certain indications.

OBJECTIVE: To present the local recurrence rates after radical cystectomy for advanced bladder cancer and to compare them between patients with orthotopic neobladder and ileal conduit. PATIENTS AND METHODS: 97 patients with radical cystectomy were analyzed: 75 patients with orthotopic ileal neobladder, operated from 1985. to 2006, and 22 patients with ileal conduit, operated from 2000. to 2006. RESULTS: Overall recurrence rate was 41.3% in the neobladder group, and 50% in the ileal conduit group. The rate of pelvic, upper urinary tract and urethral recurrence was 13.3%, 8%, and 10.6% in the neobladder group, and 9.1%, 13.6% and 9.1% in the ileal conduit group. CONCLUSION: Comparable recurrence rates, operative time, the complexity of the surgical technique and the results between two groups, strongly support the construction of orthotopic neobladder, as superior in functional, esthetic, and psychological point of view.

UNLABELLED: OBJECTIVE of this work is to evaluate interventional radiology modalities such as balloon catheter dilation (BCD) and stent insertion, as minimally invasive methods in treatment uretero-enteral anastomotic strictures. MATERIAL AND METHOD: Retrospective study enrolled 26 patients (pts) in whom percutaneous BCD (17 pts) and metal stent implantation (9 pts) were done. Study was conducted from June 2005 till August 2007 and included total amount of 470 pts operated during 4 year period from 2003 till 2007. In 26 pts 35 ureteral units were treated, all of them in ambulatory conditions under oral analgosedation, monitored by fluoroscopy. Percutaneous BCD or stent implantation was performed in 24 pts and in 2 pts combined antegrade-retrograde approach for stent delivery, was applied. In all cases percutaneous nephrostomy (PCN) was left for 7 days period after procedure but in 6 units (5 pts) it remained permanent solution. First check up was done 7 days after by contrast media injection through nephrostomy tube prior to its extraction. Second control was done 30 days after by ultrasound exam and the last control (3 months after) by intravenous urography (IVU). RESULTS: In our specimen 17pts had strictures unilaterally (65.4%) and in 9 pts (34.6%) it occurred bilaterally. First check up revealed 82.7% success of BCD, in 17.3% BCD was repeated with the final success rate of 73.5% (19/26). In four pts (26.5%) after BCD reobliteration happened and PCN was left. Patent ureteral lumen was observed in 6 pts (85.7%) with stent inserted while one pt underwent surgical reintervention. No significant difference between BCD and stent insertion success rate was noticed, based upon morphological parameters (ureteral lumen diameter, pelvicaliceal system dilatation) and serum creatinin level. CONCLUSION: BCD and stent insertion showed satisfactory results (following 3 months) in ureteroenteral anastomotic stricture recanalization. They include ambulatory conditions, ability to repeat procedure, without complications -excluding restenosis which finally can be surgically treated.

Cancer of the urinary bladder is the fourth most common cancer in men and the ninth in women. Approximately 67,000 people (50,000 males and 17,000 females) develop bladder cancer each year in the United States, and 13,750 individuals (9,630 males and 4,120 females) are expected to die from it. In the showing of the morphologic characteristics of the tumors, authors underlining the increasing of the incidence, pathogenesis, premalignant lesions and the risk factors of disease.
