RESUMO

PURPOSE: Live surgery (LS) is considered a useful teaching opportunity. The benefits must be balanced with patient safety concerns. To evaluate the rate of complications of a series of urologic LS performed by experts during the Congress Challenge in Laparoscopy and Robotics (CILR). METHODS: We present a large, multi-institution, multi-surgeon database that derives from 12 CILR events, from 2004 to 2015 with a total of 224 cases. Radical prostatectomy (RP) was the most common procedure and a selection of complex cases was noted. The primary measure was postoperative complications and use of a Postoperative Morbidity Index (PMI) to allow quantitative weighing of postoperative complications. RESULTS: From 12 events, the number of cases increased from 11 in 2004 to 27 in 2015 and a total of 27 surgeons. Of 224 cases (164 laparoscopic and 60 robotic), there were 26 (11.6%) complications: 5 grade I, 5 grade II, 3 grade IIIa, 12 grade IIIb and 1 grade V, the latter from laparoscopic cystectomy. Analysis of PMI was 23 times higher from cystectomy compared to RP. CONCLUSIONS: In the setting of live surgery, the overall rate of complications is low considering the complexity of surgeries. The PMI is not higher in more complex procedures, whereas RP seems very safe.

RESUMO

INTRODUCTION: To evaluate indications for intraoperative frozen section (IFS) during robot assisted laparoscopic radical prostatectomy (RALRP) in our series. PATIENTS AND METHODS: Prospectively documented 80 patients with prostate cancer (PCa) who underwent RALRP were evaluated between June 2010 and July 2012. Patients were divided into 2 groups according to whether systematically IFS was performed or not. Group 1 (n=66) consisted of patients on whom systematic IFS was performed, Group 2 (n=14) consisted of patients on whom IFS was not performed. All recorded data evaluated and statistical analyses were performed for determining indications and predictive factors for IFS during RALRP. All patients were operated by single surgeon and IFS, pathological assessments were performed by experienced uro-pathologist. Statistical significant p value was p < 0.05. RESULTS: Mean follow-up was 15±6 (25-4) months. Pre-operative prostate volume in trans- rectal ultrasonography (TRUS) was statistically higher in Group 1 than Group 2 (p = 0.037). The other parameters were statistically similar in both groups. According to outcomes of our study IFS was a dependent factor for positive surgical margin. Additionally, the cut off value of prostate volume in TRUS for IFS was 55.5 cc for IFS. CONCLUSIONS: Preoperative measured prostate volume in TRUS may be an indicator of IFS. Therefore, more accurate information may be given to patients with prostate cancer (Pca) before RALRP by using preoperative prostate volume in TRUS.

RESUMO

INTRODUCTION: To evaluate the effects of consistency in preoperative and postoperative Gleason scores to the operation outcomes in patients who underwent laparoscopic radical prostatectomy. MATERIALS AND METHODS: 204 of 347 patients were included the study. 143 patients whose preoperative prostate biopsies were evaluated in the other Institute were not included into the study. The preoperative data of patients and operation outcomes were investigated from institute's files of patients. Patients were divided to three groups by using consistence of pre and postoperative Gleason scores. The tumor, node and metastasis classification were used for staging prostate cancer. RESULTS: Mean age was 63 and the mean PSA level was 11 ng/dl overall. In statistical analysis PSA levels, Gleason score and rate of positive score were significantly low in Group I (p < 0.05). As in operative data, nerve sparing surgical technique was performed statistical significance higher in Group 1 than other Groups. External bleeding rate of Group II was significantly lower than the other Groups. In univariate and multivariate analysis, postoperative pathologic stage was statistical significant for consistency of pre and postoperative Gleason scores. CONCLUSIONS: The modified Gleason scoring system is safe and usable for evaluating prostate biopsies and operative specimens. The consistency in pre and postoperative Gleason score effect the operation technique and also operation outcomes. Working with an experienced uro-pathologist provides to inform patients more accurate and better.

RESUMO

OBJECTIVE: The purpose of this study was to validate an algorithm recommended by current literature for the patients with acute flank pain and evaluate the validity of bedside ultrasonography (US) performed by emergency physicians (EP) as a part of this algorithm. MATERIALS AND METHODS: This prospective validation study was carried out over a 5 month period in a tertiary care hospital adult emergency department (ED) with annual attendance of 55,000. Adult patients presenting to the ED with unilateral acute flank pain during the study period were enrolled into the study consecutively. Oral consent was obtained after the protocol was briefly explained to the patient and before the administration of analgesia. A protocol form was recorded for each patient enrolled into the study, and patients were followed up under the guidance of a previously designated algorithm in the ED. Data were analysed with SPSS software. The chi2 test was used to compare the dichotomised data of patients, diagnosed with and without stones, and to select the significant parameters to be used in the logistic regression. RESULTS: Of the 227 patients enrolled, 176 were proven to have urinary tract stones. There were 122 patients discharged from ED without further investigation except urinalysis and bedside US. Of these 122 directly discharged patients, 99 had a urinary stone, and the others did not have a life threatening disorder. Four of the 227 patients were admitted to the hospital. The remaining 51 patients did not have stones detected, and their pain subsided. Having a previous history of stones, radiation of pain to the groin, accompanying nausea, and detection of pelvicalyceal dilatation using bedside US performed by the EPs were found to be the most significant parameters in determining urinary stones in logistic regression analysis. Sensitivity and specificity of these parameters were: previous history of stones 59% and 66%, radiating pain to the groin 68% and 49%, nausea 71% and 51%, and detection of pelvicalyceal dilatation by bedside US 81% and 37%. CONCLUSION: Bedside US performed by EPs could be used safely in the evaluation of patients with acute flank pain as a part of a clinical algorithm. Previous history of urinary stones, radiation of pain to the groin, accompanying nausea. and detection of pelvicalyceal dilatation are major parameters and symptoms of urinary stone disease, and could be used in the algorithms.

RESUMO

OBJECTIVE: To compare outcomes of open (O-), laparoscopic (L-) and robot-assisted laparoscopic (RAL-) radical prostatectomy (RP) performed by the same surgeon. PATIENTS AND METHODS: From May 1999 to April 2012, 484 RPs were performed by a single surgeon. Patients' data including age, body-mass index, serum prostate specific antigen (PSA) level, Gleason score of prostate biopsy and prostatectomy specimen, preoperative prostate and specimen volumes, clinical and pathologic stages, operation time, estimated blood loss (EBL), catheterization time, blood transfusion rate were recorded. Prospectively collected data was evaluated retrospectively by statistical analyses. RESULTS: Of 484 radical prostatectomies, ORP (50), LRP (308) and RALRP (79) done by the same surgeon were included into study. Mean ages were 63.8, 62.7 and 60.3 years for ORP, LRP and RALRP respectively. Operation times for ORP, LRP and RALRP were 255, 208 and 242 minutes. EBL and hospitalization time were 602, 526, 234 mL, and 9.1, 3.2, 3.2 days for ORP, LRP and RALRP, respectively. While a significant advantage was found for EBL and complication rates in RALRP and for operation time in LRP, significant disadvantages were found in terms of catheterization time, hospitalization time, decrease in hemoglobin and blood transfusion in ORP. However, preoperative prostate volume and serum PSA level, oncologic outcomes and positive surgical margins were nearly similar in all operative techniques. CONCLUSIONS: Minimally invasive techniques such as LRP and RALRP are promising techniques with comparable outcomes with ORP. Shorter catheterization time, less blood loss and fewer complication rates can be provided by RALRP.

RESUMO

AIM: The aim of this paper was to determine whether laparoscopic adrenalectomy (LA) is a safe and effective treatment for the management of large adrenal tumors. METHODS: We retrospectively evaluated the data of patients who underwent LA at our institution between September 2002 and September 2012. Seventy-six transperitoneal LA were performed by the same surgical team. Patients with invasive tumors to adjacent organs or distant metastasis were excluded from the study. All patients were operated using the 450 oblique position as transperitoneal approach. RESULTS: The mean age of the patients was 48.3 years (range 20-68 years). The mean tumor size was 5.37 cm (range 2-15 cm). Sixteen patients had tumor size over 8 cm. The mean tumor weight was 31.2 gr (range 2-156 g). The lesions were localized on the right side in 42 (55%) patients and on the left side in 34 (45%) patients. The mean intraoperative blood loss was 114 mL (range 20-400 mL) and the mean operative time was 112 min (range 55-300 min). Six patients (7%) required conversion to open procedure. The mean hospitalization time was 2.5 days (range 1-4 days). Five patients (6%) had post-operative minor complications. There were no incidents of capsular invasion or adverse cardiovascular events. CONCLUSION: LA is safe and feasible for both malign and benign adrenal lesions. Good preoperative assessment, surgical skills, team work and adherence to anatomical and surgical principles are the key to success for large adrenal masses.

RESUMO

The existence and importance of patients with low penile buckling pressure and normal penile hemodynamic status have been recently recognized. We assessed the ratio of inadequate erection for vaginal penetration (low buckling pressure) in patients with normal penile vascular system proved with penile Doppler ultrasonography. A total of 101 patients with normal penile vascular status were retrospectively scrutinized dependent on penile axial rigidity (buckling pressure). Ninety patients had sufficient penile axial rigidity (> or = 550 g) whereas in the remaining 11 patients (11%) inadequate penile buckling pressure for vaginal penetration (< 550 g) was determined. Penile geometric and mechanical properties should not be overlooked during the evaluation of penile vascular system lest the patient be incorrectly diagnosed as having psychogenic impotence.

RESUMO

The inhibitory effect of the overactivity of the sympathetic nervous system that results from outpatient clinical conditions leads to poor erectile response to intracavernous injection of papaverine. The effects of self manual genital stimulation for improvement of erectile quality in insufficient papaverine response were investigated in 171 impotent men. Twenty-nine (63.04%) of 46 patients who had a normal vascular system showed partial response to papaverine. Following self manual genital stimulation, full erection was achieved in all of them. Better erections were achieved in 28 of 42 patients with arterial disease. In patients subclassified as having slight, moderate, and severe arterial disease, improved erections were noted in 100%, 71.42%, and 64.28%, respectively. In the mixed vascular (arterial+venous) disease group (n = 46), the combined intracavernous injection of papaverine and stimulation (CIS) test led to a better erection in only 41.30%, whereas in the pure venogenic group (n = 37), this percentage was 66.66%. The inhibitory effect of the overactivity of the sympathetic nervous system is significantly reduced by the CIS test.

RESUMO

Cellular proliferation programmed cell death (apoptosis) are associated with tumor growth in general, and prostate cancer growth in particular. The aim of this study was to examine the expression of the apoptosis regulating genes bcl-2 and p53 and Gleason score in core needle biopsy specimens of prostate cancer using immunohistochemistry. We studied bcl-2 and p53 expression in 12 cases of low grade (Gleason score 2-5), 12 cases of intermediate grade (Gleason score 6-7) and 8 cases of high grade (Gleason score 8-10) prostate cancer. Overexpression of bcl-2 was noted in 3 of 32 patients (9.32%). One of them was high grade; others were intermediate grades. Expression of p53 was observed in 3 of low grades; others were high grade. The statistical analysis of present data suggest that there is no significant relation between p53 and bcl-2 expression and Gleason score in prostate cancer.

RESUMO

BACKGROUND AND PURPOSE: To demonstrate the operative steps of transperitoneal laparoscopic radical prostatectomy with the ascending approach (Heilbronn technique). PATIENTS AND METHODS: The technique is based on our experience with more than 1000 cases of clinically localized prostate cancer from March 1999 to April 2004. The technical steps, instrumental requirements, patient data, complications, and reintervention rate were reviewed. RESULTS: The principles of the technique include the routine use of a voice-controlled robot (AESOP) for the camera, exposure of the prostatic apex with 120 degree retracting forceps, free-hand suturing for Santorini plexus control, application of 5-mm clips during the nerve-sparing technique, control of the prostatic pedicles by 12-mm Hem-o-Lock clips, the bladder neck-sparing technique in patients with stage T1c and T2a tumors, and use of interrupted sutures for the urethrovesical anastomosis. A considerable improvement was observed when comparing the first 300 with the most recent 300 cases (mean operating time 280 v 208 minutes; conversion rate 2.7% v 0.3%; reintervention rate 3.7% v 1.0%). CONCLUSIONS: Through our experience with more than 1000 cases, transperitoneal access for laparoscopic radical prostatectomy has proven to be feasible and transferable with results comparable to those of the original open approach. Besides the well-known advantages of minimally invasive surgery, the video endoscopic approach may offer further benefits in permitting optimization of the technique by video assessment.

RESUMO

In an uncontrolled study, the efficacy of azithromycin in the treatment of non-gonococcal urethritis was assessed in 41 male patients aged between 20 and 40 years with a mean age of 27 +/- 5 years. Clinical and microbiological diagnosis confirmed that 28 men were found positive for Chlamydia trachomatis, 10 for Ureaplasma urealyticum and three for both C. trachomatis and U. urealyticum. All patients received 1 g azithromycin orally (four 250 mg capsules). The length of time between the treatment and following visits were 7-10 days and 14-21 days for second and third visits, respectively. Complete eradication was achieved in 27 out of 41 patients. Of the remaining 14, six were found positive for C. trachomatis and were excluded as they did not return for the follow-up visit, one patient did not achieve complete eradication, one patient infected with both C. trachomatis and U. urealyticum failed to achieve complete eradication, and six patients infected with U. urealyticum failed to be completely cured. No adverse effects were reported in any patient. Single dose administration of 1 g azithromycin appears to be an effective and well-tolerated treatment for chlamydial urethritis and an advantage in terms of patient compliance.

RESUMO

The objective of this study was to investigate mast cells and iNOS expression in testis tissue, and to correlate these results with spermatogenic disorders. A total of 136 testicular biopsies were obtained from the testes of 80 patients with infertility. Their age ranged from 21 to 45 years. The biopsy specimens were immunohistochemically stained with antihuman tryptase for mast cells. In each section, all interstitial fields were evaluated for the total number of mast cells as well as the total number of Leydig cells. The number of mast cells per Leydig cell was calculated and recorded as mast cell index. Immunohistochemical iNOS staining was evaluated semiquantitatively according to intensity and the proportion of the stained cells. There was a significant increase of the mast cell index in all groups with testicular disorder compared with normal spermatogenesis group (p < 0.05). Increase of the index was in the order of hypospermatogenesis, maturation arrest and SCO, and index of SCO group was especially higher, i.e, more than twice than other groups. iNOS score was significantly higher in the SCO group than in the men with normal spermatogenesis, hypospermatogenesis, and maturation arrest (p < 0.05). Finally, a significantly statistical correlation was found between the iNOS score and mast cells index (r = 0.758, p = 0.001). Increase of mast cell index was observed in the groups of infertile testis, and high expression of iNOS in Leydig cells was associated with the highest mast cell index in SCO, the lesion with the most severe damage of the germ cell.

RESUMO

OBJECTIVE: Color Doppler ultrasonography is a useful method in the evaluation of small vessels and vascular anatomy and in demonstrating dynamic changes of blood flow. The detrimental effects of different risk factors of erectile dysfunction such as diabetes mellitus, hypertension, hypercholesterolemia on the penile arterial system were investigated. METHOD: 180 patients with erectile dysfunction underwent functional evaluation of the arterial system by combined intracavernous injection of 60 mg papaverine and stimulation test and color Doppler ultrasonography. RESULTS: There were 64 patients (35.55%) whose vascular findings were normal. A total of 36 patients (20.00%) had arterial insufficiency and 42 patients (23.33%) had mixed-arteriogenic-venogenic impotence. Combination of hypertension and hypercholesterolemia was found to be more detrimental to the penile arterial system than hypertension alone, the presence of hypertension and diabetes mellitus together, diabetes alone and hypercholesterolemia. CONCLUSION: Color Doppler ultrasonography depends on variables such as equipment, operation and software version in the functional evaluation of the penile arterial system. The combination of hypertension and hypercholesterolemia was found to be more detrimental to the penile arterial system. Further studies based on larger patient populations are required in order to determine the effects of erectile dysfunction contributing disease on the penile arterial system.

RESUMO

OBJECTIVE: A positive intracavernous papaverine test has been presumed to determine normal erectile hemodynamics. Recently, positive erectile responses to intracorporeal injection tests were reported in patients with penile arterial insufficiency. METHODS: This hypothesis was assessed by obtaining hemodynamic data using color Doppler ultrasonography in 417 patients with erectile dysfunction aged between 20 and 73 years (mean 43.06 +/- 13.66). A normal penile vascular system was found in 95 patients (22.79%), veno-occlusive dysfunction in 76 (18.22%), arteriogenic erectile dysfunction (ED) in 113 (27.10%) and mixed-type ED in 133 (31.89%). RESULTS: A positive erection response was achieved in 176 patients with combined intracavernosal injection of 60 mg papaverine and self-manual genital stimulation (CIS) test, while a negative response was observed in the remaining 241 (57.79%). Color Doppler ultrasonography combined with pharmacological erection has proved a normal penile vascular system in 94 (53.41%) and penile arterial insufficiency in 82 (46.59%) patients of those who gave a positive response to the CIS test. Also, a positive CIS test response was observed in all patients with unilateral arterial insufficiency (n = 31) and in 51 patients (62.19%) out of 82 with bilateral arterial insufficiency. CONCLUSION: A positive intracavernous papaverine test indicates veno-occlusive dysfunction competence but does not necessarily signify a normal penile arterial system. The CIS test should be combined with color Doppler ultrasonography in order to determine the vascular component of ED, since the differentiation is not possible between slight penile arterial insufficiency and psychogenic or neurogenic impotence with the CIS test.

RESUMO

OBJECTIVE: With continuous improvements in ultrasound technology, small vessels with remarkably slow blood flow that may not be assessed by color Doppler ultrasonography, can be evaluated using power Doppler ultrasonography. In the present study, penile arterial anatomic variations were determined with power Doppler ultrasonography and its impact on penile hemodynamic status. METHODS: A total of 54 patients with erectile dysfunction were evaluated with power Doppler ultrasonography. The effects of vascular anatomic variations and the structure of the corpora cavernosa and tunica albuginea on vascular status were assessed on both sides. RESULTS: A normal penile vascular system was observed in 35.2% and 25% of 54 patients (mean age: 46.6+/-11.5 years) at the radix and mid-shaft of the penis, respectively. Pure arterial component was observed in 40.7% (22/54) and 47.2% (17/36) of the patients at the base and mid-shaft of the penis, respectively. Penile arterial insufficiency was severe in 9.2 and 5.5% of the patients at the base and mid-shaft of the penis, respectively, whereas intrapenile truncus was found in six patients (5.5%), the ratio of single cavernosal artery, intrapenile and extrapenile bifurcations were 69.4, 7.4 and 12.0%, respectively. Twenty (18.5%) dorso-cavernosal perforators, 15 (13.9%) cavernoso-dorsal and 30 (27.8%) intercavernosal branches were found. Peak systolic blood flow velocity values were decreased in 12 of 36 patients (33.3%) distally, while increased blood flow was observed in 11 (30.5%). CONCLUSIONS: Hemodynamic parameters might be variable at either side of the penis and depend on intrapenile arterial anatomic variations. Parameters determined using power Doppler ultrasonography should be evaluated from the proximal to distal side of the penis to obtain reliable and standard results. However, variations of penile arterial anatomy and its effect on penile hemodynamic changes should not be overlooked especially in the patients who are candidates for penile reconstructive or vascular surgery.

RESUMO

OBJECTIVES: Cavernosometry is a conventional and reliable method used in the diagnosis of caverno-venous incompetence. Recently, cavernosal artery end-diastolic blood flow velocity more than 5 cm/sec during the rigid phase and after 10 minutes with duplex ultrasonography has been considered as veno-occlusive dysfunction. METHODS: Fifteen patients with erectile dysfunction aged 20 to 56 years (mean age 35.8) were evaluated by dynamic infusion cavernosometry and duplex ultrasonography which measured end-diastolic blood flow velocity during the rigid phase of erection and after 10 minutes. RESULTS: Dynamic cavernosometry was considered the gold standard during this comparative study. The sensitivity of duplex ultrasonography was found to be 100%, its specificity was 71.42%, positive predictive value 80% and its negative predictive value was 100% in the detection of caverno-venous incompetence.

RESUMO

The direct evaluation of the autonomic nervous system to detect the neurogenic component of erectile dysfunction in men is not possible. Biothesiometry, a vibration perception test, is a simple method for the assessment of the penile somato-afferent system. A nomogram for the evaluation of somato-afferent system has been developed utilizing the biothesiometer in healthy men. This nomogram was used to compare the biothesiometric values of potent and impotent diabetic patients. According to our data, the radix penis is selectively damaged by diabetes mellitus in the first stage of the disease, whereas the glans penis is damaged later on when the disease reaches the stage of impotence.

RESUMO

The signet ring cell carcinoma of the urinary bladder is a rare neoplasm; the 70 cases found in the literature pursued a fulminant and mostly fatal course; the neoplasms diffusely invaded the bladder wall without forming intraluminal growths and could not be controlled by segmental resection, radiotherapy and chemotherapy alone or in combination. We herewith present 2 cases of primary signet ring cell carcinoma of the urinary bladder--one associated with high-grade transitional cell carcinoma and in situ carcinoma--and review the literature.

RESUMO

OBJECTIVES: Honeymoon impotence is the inability to perform successful sexual intercourse during the initial experience, especially during the first nights of marriage, and it is relatively frequent in Turkey. We investigated the underlying penile vascular abnormalities in patients presenting with honeymoon impotence and sought to differentiate between psychogenic and organic etiologies. METHODS: Between 1989 and 1999, 90 patients sought urologic help for honeymoon impotence. Patient age ranged from 18 to 39 years (mean 28.06 +/- 3.4). All patients were given an intracavernous injection of 60 mg papaverine combined with self-manual genital stimulation (CIS test) to assess the degree of tumescence. Patients with a positive response to the CIS test were later evaluated with nocturnal penile tumescence (NPT) monitoring. Patients with a negative response to the CIS test and/or NPT monitoring were evaluated further using penile color Doppler ultrasound. RESULTS: A psychogenic etiology was found in 61 patients (67.7%), 50 (55.5%) of whom achieved satisfactory sexual intercourse after intracavernous injection. Twenty-five patients (27.7%) exhibited penile vascular abnormalities by color Doppler ultrasound. Neurogenic erectile dysfunction was considered in the remaining 4 patients (4.4%) with a positive response to the CIS test, abnormal findings on NPT monitoring, and a normal vascular system with color Doppler ultrasound. CONCLUSIONS: The present study is the first to report penile vascular abnormalities in patients presenting with honeymoon impotence, which was previously believed to be exclusively psychogenic in origin. The evaluation of the penile vascular system in patients with honeymoon impotence may reveal underlying penile vascular abnormalities, allowing the choice of the appropriate therapeutic option.

RESUMO

OBJECTIVE: To determine whether preoperative usage of alpha-1 adrenoceptor antagonists (alpha-1ARA) prevents the alterations in bladder wall components due to obstruction via changing apoptotic and/or proliferative activity and provides an advantage for improvement of irritative symptoms following removal of bladder outlet obstruction. MATERIAL AND METHODS: A total of 39 patients were enrolled to the present study. According to preoperative medical treatment, patients were divided into 2 groups as preoperative untreated (n = 15) and medically treated patients with alpha-1ARA (n = 24). Apoptotic and proliferative indices of bladder wall were determined with TUNEL assay and proliferating cell nuclear antigen immunoreactivity, respectively. RESULTS: While the mean apoptotic indexes (AI) of lamina propria were 0.293 +/- 0.163 vs 0.978 +/- 0.194 in untreated and treated patients, the mean AI of myofibroblast cells were 0.10 +/- 0.06 and 0.90 +/- 0.23 in untreated and treated patients, respectively. There were statistically significant differences between lamina propria (p = 0.0067) and myofibroblast cells (p = 0.0280) AI in the two groups. However, there were no significant differences between postoperative symptom indices in preoperatively treated and untreated groups. CONCLUSIONS: alpha 1-ARA treatment might have an effect on hypertrophy and supersensitivity of bladder wall due to increased outlet obstruction via prevention of the imbalance between cell proliferation and apoptosis, providing normal homeostatic control mechanisms, through the interval between the onset of the lower urinary tract symptoms and time surgical intervention. However, further studies should be organized to demonstrate the impact of long-term alpha 1-ARA medication for post-operative significant improvement on irritative symptom index.
