RESUMO

ABSTRACT Purpose: We aimed to compare the success and complication rates of the anterograde and retrograde Ureterorenoscopy (URS) for impacted upper ureteral stones in patients > 65 years of age. Materials and Methods: Data of 146 patients >65 years of age and underwent anterograde URS (n=68) in supine position or retrograde URS (n=78) for upper ureteral impacted stones>10 mm between January 2014 and September 2018 were collected prospectively. The groups were compared for success and complication rates, duration of operation, hospital stay, and ancillary procedures. Results: Anterograde and retrograde URS groups were similar for demographic and stone related characteristics. The success rate of the anterograde URS group was significantly higher than the retrograde URS group (97.1% vs. 78.2%, p=0.0007). The complication rates were similar for the two groups (p=0.86). Clavien grade I and II complications were observed in 3 patients in each group. The mean hemoglobin drop was 0.5 g/dL in the anterograde URS group and blood transfusion was not performed in any of the patients. The mean duration of operation was 41.2±12.5 minutes in the mini-PNL group and 59.6±15.1 minutes in the RIRS group and the difference was statistically significant (p=0.02). The median duration of hospitalization was 1 day for both groups. Conclusions: Performing anterograde URS in supine position provided better success rates and similar complication rates compared to retrograde URS. Based on these results anterograde URS shall be considered as one of the primary treatment options for management of impacted upper ureteral stones in the elderly population.

RESUMO

OBJECTIVE: To evaluate the effects of location of the tip of percutaneous sheath and nephroscope in the collecting system together with active aspiration on the Intrapelvic pressure measurements (IPP) during miniaturized percutaneous nephrolithotomy (miniPNL). MATERIALS AND METHODS: The data of 20 patients underwent miniPNL in supine position was collected prospectively. IPP measurements were done with an 8 Fr urodynamic pressure measurement catheter in 4 different settings with respect to location of tip of sheath and nephroscope. All 4 settings were repeated with active aspiration. Totally measurements were done and compared in 8 different settings for 90 seconds in each patient. RESULTS: Highest mean IPP measurements were recorded in setting II (35.3 ± 11.8 cm H2O) where the sheath was located in the calyx and the tip of the nephroscope was in the renal pelvis. When active aspiration was applied, the mean pressure measurements were significantly lower than the counterpart settings without aspiration (all P values <.0001). When the active aspiration was applied, intrarenal pressure measurements did not exceed 40 cm H2O in any settings in any of the patients. CONCLUSION: Location of the tip of the sheath and the nephroscope has significant effect on IPP measurements. Active aspiration significantly lowers the IPP and keeps it <40 cm H2O. Endourologists should be aware of possible alterations in IPP during miniPNL and active aspiration should be kept in mind as an effective solution to decrease the risk of complications related to high IPP.

RESUMO

OBJECTIVE: We aimed to evaluate the effect of body mass index (BMI) on oncological and surgical outcomes in patients who underwent radical cystectomy (RC) for bladder cancer (BC). MATERIALS AND METHODS: We retrospectively assessed data from patients who underwent RC with pelvic lymphadenectomy and urinary diversion for BC recorded in the bladder cancer database of the Urooncology Association, Turkey between 2007 and 2019. Patients were stratified into three groups according to the BMI cut-off values recommended by the WHO; Group 1 (normal weight, <25 kg/m2), Group 2 (overweight, 25.0-29.9 kg/m2) and Group 3 (obese, ≥30 kg/m2) RESULTS: In all, 494 patients were included, of them 429 (86.8%) were male and 65 (13.2%) were female. The median follow-up was 24 months (12-132 months). At the time of surgery, the number of patients in groups 1, 2 and 3 were 202 (40.9%), 215 (43.5%) and 77 (15.6%), respectively. The mean operation time and time to postoperative oral feeding were longer and major complications were statistically higher in Group 3 compared to Groups 1 and 2 (p=0.019, p<0.001 and p=0.025 respectively). Although the mean overall survival (OS), cancer-specific survival (CSS), recurrence-free survival (RFS) and metastasis-free survival (MFS) was shorter in cases with BMI ≥30 kg/m2 compared with other BMI groups, differences were not statistically significant (p=0.532, p=0.309, p=0.751 and p=0.213 respectively). CONCLUSION: Our study showed that, although major complications are more common in obese patients, the increase in BMI does not reveal a significant negative effect on OS, CSS, RFS, and MFS.

RESUMO

OBJECTIVE: To present a nation-wide analysis of the workload of urology departments in Turkey week-by-week during Covid-19 pandemic. METHODOLOGY: The centres participating in the study were divided into three groups as tertiary referral centres, state hospitals and private practice hospitals. The number of outpatients, inpatients, daily interventions and urological surgeries were recorded prospectively between 9-March-2020 and 31-May-2020. All these variables were recorded for the same time interval of 2019 as well. The weekly change of the workload of urology during pandemic period was evaluated, also the workload of urology and the distributions of certain urological surgeries were compared between the pandemic period and the same time interval of the year 2019. RESULTS: A total of 51 centres participated in the study. The number of outpatients, inpatients, urological surgeries and daily interventions were found to be dramatically decreased by the 3rd week of pandemics in state hospitals and tertiary referral centres; however, the daily urological practice were similar in private practice hospitals throughout the pandemic period. When the workload of urology in pandemic period and the same time interval of the year 2019 were compared, a huge decrease was observed in all variables during pandemic period. However, temporary measures like ureteral stenting, nephrostomy placement and percutaneous cystostomy have been found to increase during Covid-19 pandemic compared with normal life. CONCLUSIONS: Covid-19 pandemic significantly affected the routine daily urological practice likewise other subspecialties and priority was given to emergent and non-deferrable surgeries by urologists in concordance with published clinical guidelines.

RESUMO

PURPOSE: To investigate the role of urinary neutrophil gelatinase-induced lipocalin (uNGAL) measurement in the early diagnosis of acute kidney injury that may occur after intraoperative ischemia in patients undergoing partial nephrectomy (PN). METHODS: This prospective study included 86 patients who underwent open laparoscopic or robotic partial nephrectomy between May 2017 and May 2019. During the surgery, whether the patients had ischemia or not, type of vascular clamping and the ischemia time were noted. The definition of acute kidney injury (AKI) was classified according to Acute Kidney Injury Network (AKIN) criteria. Urine samples were collected preoperatively and 3 h after renal pedicle clamp removal and uNGAL was measured. RESULTS: AKI was recorded in 34 (39.5%) of 86 patients after PN. Of the 34 patients, 26 (76.4%) had level 1 and 8 (23.6%) had level 2 AKI. uNGAL levels increased significantly as an early reflection of AKI in patients who underwent intraoperative total or renal artery clamping (p = 0.024). There was no significant postoperative increase in uNGAL in the non-ischemic group (p = 0.163). uNGAL expression was detected well before serum creatinine increase. Patients with AKI after PN had higher uNGAL expression (p = 0.008) However, there was no correlation between the level of AKI and uNGAL expression (r = 0.201, p = 0.066). CONCLUSION: Ischemic acute kidney injury after nephron-sparing surgery can be detected early by uNGAL measurement. In future studies comparing outcomes of different surgical techniques on renal functions after PN, uNGAL levels may be used.

RESUMO

AIM: To validate the Turkish versions of the interstitial cystitis symptom index (ICSI) and interstitial cystitis problem index (ICPI) for use in Turkish speaking patients with bladder pain syndrome/interstitial cystitis (BPS/IC). METHODS: After translation of the original ICSI and ICPI into the Turkish language, Turkish versions of ICSI and ICPI were self-administered to all participants. Test-retest reliability (intraclass correlation coefficient) was evaluated at 2 weeks intervals in the BPS/IC group. Internal consistency was evaluated using Cronbach's alpha. Scores of ICSI and ICPI was compared between BPS/IC and control groups to examine discriminant validity. Criterion validity was examined via investigating the correlations between bladder diary data (24-hour frequency and nocturia), visual analogue scale (VAS) scores, and results to the corresponding questions in ICSI and ICPI. RESULTS: Results of 79 patients with BPS/IC and 50 control patients were analyzed. Both indices showed high internal consistency (Cronbach's α for ICSI and ICPI was 0.879 and 0.923, respectively). The test-retest reliability of ICSI and ICPI was high for total scores and subdomains of both indices (intraclass correlation coefficient was 0.722 for ICSI and 0.777 for ICPI). Scores of both indices were significantly higher in BPS/IC group than the control group (P < .001). Statistically significant correlations were found between 24-hour frequency, nocturia, VAS scores, and corresponding questions in the indices. A statistically significant and strong correlation was observed between ICSI and ICPI scores (P < .001, rS = .632). CONCLUSION: Turkish versions of ICSI and ICPI are reliable, consistent, and valid instruments to evaluate symptoms of Turkish speaking patients with BPS/IC.

RESUMO

BACKGROUND: The aim of this study was to evaluate predictive factors of 68Gallium (68Ga) prostate-specific membrane antigen (PSMA) positron emission tomography (PET)/computed tomography (CT) positivity. METHODS: Relationships between serum prostate specific antigen (PSA), lactate dehydrogenase (LDH) and alkaline phosphatase (ALP) levels, Gleason Score (GS) and positivity of 68Ga PSMA PET in patients who underwent 68Ga PSMA PET/CT for restaging for PCa were evaluated retrospectively. RESULTS: One hundred and four (median age: 67; range: 51-88) patients were included in this study. Of these patients, PSMA PET was positive in 75 (72%) patients. Mean serum PSA levels for PET negative and positive groups were 0.76±1.00 and 180.85±324.93 ng/mL (P<0.001). The sensitivity and specificity of 68Ga PSMA PET/CT for detection of disease recurrence were calculated as 92% and 80%, respectively, for the 1.4 ng/mL PSA cut-off and 92% and 90%, respectively, for the 2 ng/mL PSA cut-off values. The positivity rates for patients with PSA levels <1.4 ng/mL and ≥1.4 ng/mL were 21% and 90%, respectively (P<0.001). CONCLUSIONS: 68Ga PSMA PET/CT seems to be a highly sensitive in patients with early PSA recurrence. Patients with higher GS and early PSA recurrence could benefit from 68Ga PSMA PET/CT.

RESUMO

OBJECTIVE: To determine the possible role of potassium sensitivity test (PST) in predicting the success of hydrodistention (HD) in patients with bladder pain syndrome/interstitial cystitis (BPS/IC). MATERIAL AND METHODS: Patients who underwent PST before diagnostic cystoscopy and HD were evaluated to collect data regarding the visual analog score (VAS) to assess pain, the voiding diary for frequency of urination/nocturia, mean urine volume per void, interstitial cystitis symptom index, and problem index before HD. Patients were requested to provide the VAS of pain at 1 month and 6 months post-HD. A reduction 2 or more on the VAS of pain was considered as a response adequate to be noted. RESULTS: The median age of the patients was 46 years. The PST was positive for 27 patients (27/39; 69.2%). At 1 month post-HD, out of the 27 patients with positive PST, 23 (85.2%) were found to have been responsive to HD and 4 (14.8%) were non-responsive. Of the 12 (12/39; 30.8%) patients who showed a negative PST, 7 (58.3%) were non-responsive and 5 (41.7%) were responsive to HD. A logistic regression analysis revealed that PST (p=0.009) was the only parameter that was able to predict HD efficacy at 1 month post-HD. CONCLUSION: PST was found to be a predictive factor for the short-term efficacy of HD. BPS/IC patients with positive PST are likely to be more susceptible to the damage of mucosal afferent nerve endings, which results in them benefiting from HD to a greater degree.

RESUMO

OBJECTIVE: The supine position is becoming increasingly popular in percutaneous nephrolithotomy (PNL). Renal puncture is the key step for a successful PNL procedure. The aim of this study was to describe a novel method for renal puncture and compare it with a previously described method. MATERIAL AND METHODS: Data of 358 patients who underwent PNL in the supine position were collected prospectively. In 165 patients, the puncture was performed by a previously described method (Group 1), and in 193 patients, the puncture was performed with the novel method (Group 2). Groups were compared with regard to total time and fluoroscopy time to successful puncture. In the novel puncture technique, the needle is advanced toward the targeted calyx under monoplane fluoroscopy. To determine the needle depth, the C-arm is rotated by 10°. If the needle projection is beyond the targeted calyx in fluoroscopy, the puncture is deeper than desired. If the needle projection does not reach the targeted calyx, the puncture is more superficial than desired. RESULTS: Groups were similar with regard to the mean age, gender distribution, body mass index, stone size, and site of puncture. The mean total time to puncture was 88.2±25.3 seconds in Group 1 and 54.3±22.3 seconds in Group 2, and the difference was statistically significant (p=0.03). The mean fluoroscopy time to puncture was 16.1±5.3 seconds in Group 1 and 9.3±3.4 seconds in Group 2, and the difference was statistically significant (p=0.03). CONCLUSION: This novel method to determine the depth of the needle is simple, reproducible, and has the potential to diminish radiation exposure with the aid of intermittent fluoroscopy.

RESUMO

ABSTRACT Introduction: The main aim of stone surgery is to establish stone free status. Performing flexible nephroscopy is an effective tool in this manner. The aim of this study was to evaluate the role of retrograde flexible nephroscopy for detection of residual fragments following percutaneous nephrolithotomy (PNL) in comparison with antegrade approach. Materials and Methods: Data of 137 patients underwent ECIRS was collected prospectively. In all cases following stone clearance, collecting system was checked for residual fragments. First antegrade than retrograde flexible nephroscopy was performed and success rates to reach all calices and detection of residual fragments were noted. All patients underwent CT and success rate of antegrade and retrograde approaches were compared. PPV and NPV of retrograde approach to detect residual fragments were calculated. Results: Antegrade and retrograde nephroscopy successfully accessed all of the calices in 101 (73.7%) and 130 (94.9%) patients respectively (p<0.0001). Residual fragments were observed in 18 (13.1%) patients following antegrade flexible nephroscopy. Retrograde approach identified residual stones in 17 more cases. These cases were treated with flexible nephroscopy or secondary percutaneous tract. Postoperative CT revealed residual stones in 10 (7.3%) patients. PPV and NPV of retrograde flexible nephroscopy were 83.3% and 96.2%. Conclusions: Flexible nephroscopy effectively detects residual fragments following PNL. Retrograde approach was more successful than antegrade approach to reach all calices. We recommend performing retrograde flexible nephroscopy following PNL especially in complex cases as it has the potential to increase SFR, decrease the need for second look surgery and unnecessary postoperative imaging.

RESUMO

The incidence of second primary cancer detection in patients with prostate cancer undergoing cross-sectional imaging for staging workup is 1.5%.1 Concomitant prostate cancer and clear-cell renal cell carcinoma is a rare condition. The coexistence of 2 synchronous neoplasm is highly infrequent. In this case, we present a combined robot-assisted operation for both procedures concurrently with a port strategy allowing reuse of ports.

RESUMO

PURPOSE: To investigate the prognostic role of time to castration resistance(TTCR) in patients who have received solely Docetaxel chemotherapy regimen(DCR) for castration resistant prostate cancer(CRPC). METHODS: Between Jan 2004 and Dec 2015, data of 162 patients who have received DCR for CRPC were gath-ered. Patients were divided into three groups according to TTCR: Group 1(? 12 months), group 2(13-24 months), and group 3(>24 months). Data of age, clinical stage, Gleason grade(GG), previous treatments, site of metastases, Prostate-specific antigen (PSA) values, TTCR, overall survival, biochemical progression free survival(PFS) and PSA response to docetaxel were recorded. RESULT: The mean age of the 162 patients was 74.4 ± 8.5 years. Data on mean age, type of castration, adding estra-mustine to docetaxel, secondary hormonal manipulation, Gleason grade, clinical T stage at initial diagnosis and site of metastases were comparable between three groups. PSA values were higher in group 1 than other groups. PSA response to docetaxel was 59.2% in all patient and it was worse in group 1 than other groups (P = .009). Two years overall survival rates were 7.6%, 25% and 32.3% in group 1, 2 and 3, respectively. Median survival rates were 7, 14 and 23 months in group 1, 2 and 3, respectively, and this difference was statistically significant (P=.016). On multivariate analysis, TTCR was found to be independent prognostic factor for overall survival and response to docetaxel treatment. CONCLUSION: TTCR appears to be an independent prognostic factor for patients who are candidates for DCR.

RESUMO

PURPOSE: To compare of changes in glomerular filtration rate (GFR) in patients who underwent radical cystectomy (RC) and multimodal treatment (MMT). MATERIALS AND METHODS: We identified 472 consecutive patients who underwent RC or treated with MMT for muscle invasive bladder cancer (MIBC) at our institution, between January 1995 and December 2010. After ex-cluding the patients who died within 5 years or without 5 years of follow-up, 175 and 59 patients who were treated with RC and MMT, respectively were included to the study. GFR was measured before treatment and every 6 months after treatment till the end of 60th month. RESULTS: The mean age and mean baseline GFR were 66.5±5.7 years and 85.1±18.2 mL/min/1.73m2, respectively for all patients. We detected statistically significant higher decrease rates for GFRs in MMT group compared to RC group at every follow up period till 42nd month. Renal function decreasing was found to be more prominent during first year of follow-up (79.1 to 65.9 mL/min/1.73m2) in MMT group. However, GFR decreased more reg-ularly in RC group (~4 mL/min/1.73m2 per year). MMT, lower baseline GFR, Diabetes Mellitus, hypertension, and ureteroenteric anastomotic stricture development were associated with low GFR under 60 and 45 mL/min at the end of five years. CONCLUSION: Decreased renal function is noted in many MIBC patients after RC or MMT in the long-term fol-low-up. Renal function deterioration is more prominent within the first year after MMT.

RESUMO

INTRODUCTION: Kidney displacement may alter the quality of renal puncture during percutaneous nephrolithotomy (PCNL). The aim of this study was to identify the rate of kidney displacement and parameters associated with kidney displacement in patients who underwent supine mini-PCNL. METHODS: Data of 98 consecutive patients who underwent mini-PCNL was collected prospectively. The patients were grouped as displacement-positive vs. -negative. The parameters collected were age, gender, body mass index, side of the kidney, punctured calyx, fluoroscopy time to successful puncture and tract dilation, stone-free and complication rates, stone diameter, length of the renal artery, and quantity of peri-renal and abdominal fat. Groups were compared for the above listed parameters and logistic regression analysis was performed to identify factors associated with kidney displacement. RESULTS: There were 34 and 64 patients in the displacement-positive and -negative groups, respectively. Groups were similar for stone-free and complication rates. Fluoroscopy time to puncture and tract dilation were longer in the displacement-positive group. Groups were different for renal artery length and peri-renal fat measurements. In multivariate analysis, lower pole puncture, renal artery length, and peri-renal fat measurement were found to be independent predictors of kidney displacement. CONCLUSIONS: Kidney displacement does not alter the success and complication rates, but is associated with longer fluoroscopy times during supine PCNL. In the current study, parameters in preoperative non-contrast computerized tomography (NCCT) associated with kidney displacement were identified. We recommend surgeons evaluate and take into account these parameters during preoperative planning to establish better outcomes and diminish fluoroscopy times.

RESUMO

INTRODUCTION: Intravesical glucosaminoglycan (GAG) replacement therapies are commonly used in the treatment of bladder pain syndrome (BPS)/interstitial cystitis (IC). Different intravesical glucosaminoglycan products are currently available. In this prospective study, clinical efficacy of chondroitin sulfate and hyaluronic acid are compared in patients with BPS/IC. METHODS: Patients were randomized to CS and HA groups. All patients were evaluated for visual analogue pain scale (VAS), interstitial cystitis symptom index (ICSI), interstitial cystitis problem index (ICPI), voiding diary for frequency/nocturia, and mean urine volume per void at the beginning of the therapy and after 6 months. All patients had a potassium sensitivity test (PST) initially. Wilcoxon and Mann-Whitney U tests were used for statistical analysis. RESULTS: There were 21 patients in both groups. Mean age of patients in CS and HA groups were 47.10 and 48.90, respectively(P > 0.05). Before treatment, Parson's test was positive in 64.3% of patients (27/42) with no difference between groups. VAS of pain, ICSI, ICPI, frequency at 24 h and nocturia results have improved significantly at both treatment arms. Intravesical CS was also found superior to intravesical HA in terms of 24 h frequency, nocturia and ICPI (P < 0.05). No severe adverse effects were reported. CONCLUSIONS: Data comparing clinical efficiencies of different GAG therapies are very limited. In this study, intravesical CS was found superior to intravesical HA in terms of 24 h frequency, nocturia and ICPI in patients with BPS/IC in short term follow-up. To provide a definitive conclusion on superiority of one GAG therapy to others, further evaluation with long term follow up is required.

RESUMO

OBJECTIVE: Hydronephrosis developing following ureteroscopy (URS) is an important issue associated with the long-term postoperative renal functions. Studies investigating the role of postoperative imaging revealed conflicting results. In this study, we aimed to determine the incidence and predictors of hydronephrosis following semirigid URS. MATERIAL AND METHODS: We evaluated the results of 455 patients who underwent U RS a nd postoperative imaging with non-contrast computed tomography (CT). Primary endpoints of the study were to determine the frequency of development of hydronephrosis and factors associated with the development of hydronephrosis. Logistic regression analysis was used to define factors effecting on the development of hydronephrosis. RESULTS: Postoperative non-contrast CT revealed hydronephrosis in 81 (17.8%) patients. Stone-free status was achieved in 415 (91.2%) patients. Univariate analysis revealed history of ipsilateral URS (p=0.001), duration of operation (p=0.022), presence of multiple stones (p=0.001), and occurrence of a renal colic episode postoperatively (p=0.013) as the parameters associated with increased risk of postoperative hydronephrosis. In the multivariate analysis, history of ipsilateral URS (OR: 2.724, p=0.017) and presence of multiple stones (OR: 2.116, p=0.032) were found to be the independent prognostic markers of developing postoperative hydronephrosis. CONCLUSION: Ipsilateral hydronephrosis following URS develops in a significant number of patients. In patients with history of ipsilateral hydronephrosis and multiple stones, risk of development of postoperative hydronephrosis is higher, therefore physicians should be keep these parameters in mind in the decision making process of selective imaging postoperatively.

RESUMO

INTRODUCTION: Stone disease is an important health problem, and patients have different treatment choices. Shared decision making is recommended for deciding the treatment type, but patient education is necessary. Decision aids (DAs) are used for this aim, and herein, we developed a novel DA for patients with symptomatic nonlower pole renal stones <20 mm in diameter. MATERIALS AND METHODS: The DA development process was established based on the recommended guides. General characteristics of the stone disease and details of the shockwave lithotripsy and retrograde intrarenal surgery were included in the content of the DA. The DA was further revised based on the suggestions of different physician groups and patients. The DA was evaluated by three physicians (Delphi assessment-International Patient Decision Aid Standards [IPDAS] Collaboration standards) and 25 patients (questionnaire of six questions with five-point Likert scale). RESULTS: The DA was designed as a booklet, and Delphi group assessment resulted in a total score of 50/54. Patient evaluation of the DA resulted in favorable outcomes, and patients generally recommended its use by other patients. CONCLUSIONS: This novel DA for patients with a symptomatic nonlower pole renal stone <20 mm showed promising results and was well accepted by the patients. We believe that this DA will have a positive impact on patients' level of knowledge. Increased level of knowledge will also improve the patients' contribution to the shared decision-making process. A further prospective randomized trial to compare with the standard patient informing process is also planned.
