Outcomes of ultraminipercutaneous nephrolithotomy in infants: our experiences at a single center in an endemic region.

OBJECTIVE: In this study, we aimed to contribute to the literature by sharing the perioperative and postoperative outcomes of infants (0-24 months) who underwent ultra-mini percutaneous nephrolithotomy (PNL) for kidney stones in our clinic. METHODS: Infants under 24 months old with kidney stones of 2 cm and larger, who applied to our clinic between January 2018 and May 2023, were included in the study. The patients' demographic and clinical characteristics were obtained from the medical records. The collected data were analyzed retrospectively. RESULTS: A total of 26 patients were included in the study. The mean age of the patients was 17.3 ± 3.90 (12-24) months. The mean operation time was 50.7 ± 6.43 min. The mean stone size was 2.66 ± 0.59 cm. Stone-free was achieved in 23 patients (88.5%). In one patient (3.8%) with residual fragments, SWL was performed, and in two patients (7.7%), RIRS was performed to achieve stone-free. Postoperatively, fever was observed in 3 patients (11.5%). There were no patients requiring blood transfusion. CONCLUSIONS: In experienced centers, ultra-mini-PNL performed by experienced surgeons is an effective and reliable treatment option for infants under 24 months of age with kidney stones larger than 2 cm. It provides high-stone clearance rates and low complication rates.

Effect of sex-specific abdominal fat tissue composition on WHO/ISUP nuclear grade of clear cell renal cell carcinoma.

Background/aim: To investigate the relationship between sex-related visceral obesity and WHO/ISUP nuclear grade in clear cell renal cell carcinoma (ccRCC). Materials and methods: Between January 2018 and June 2022, 95 patients (56 men and 39 women) with pathologically proven ccRCC who underwent abdominal computed tomography examination were retrospectively examined. The patients were classified into two groups: low- and high-WHO/ISUP nuclear grade ccRCC (n = 58 and n = 37), respectively. Patient height, weight, body mass index (BMI), sex, age, subcutaneous fat area (SFA), visceral fat area (VFA), total fat area (TFA), and percentage of visceral fat (VF%) were recorded for the two groups. Results: No significant differences were found in age, BMI, SFA, or TFA, but VFA and VF% were significantly higher in the high-grade patient group. In males, maximal tumor diameter (MTD) (67.8% sensitivity and 76.9% specificity) had the highest area under the curve (AUC), while in females, VF% (70.0% sensitivity and 73.7% specificity) had the highest AUC. VF% revealed an odds ratio (OR) of 1.09 in females with high-grade ccRCC, and in males, MTD was an independent predictor of ccRCC with an OR of 1.03. Conclusions: Sex-related body fat tissue, including VFA and VF%, could be used for estimating WHO/ISUP nuclear grade in patients with ccRCC, especially in females.

Treatment management of COVID-19 positive patients with renal colic secondary to distal ureteral stone.

OBJECTIVE: In this study, we aimed to contribute to the literature by sharing and evaluating the clinical characteristics and our treatment and follow-up approaches in patients in the COVID-19 positive treatment process who had presented to our hospital's emergency department with a distal ureteral stone and to examine the effects of the pandemic and disease in this group of patients. METHOD: The study included 14 patients infected with COVID-19 who had presented to the Erzurum City Hospital Emergency Department between August 2020 and December 2020 with the complaint of renal colic in which distal ureteral stones were detected in the tests. The demographic and clinical characteristics of patients, laboratory and radiological examinations, characteristics of ureteral stones, details of treatments applied to patients, treatment procedures of patients who had undergone surgical treatment, patient files, visit and operation notes and the patient discharge reports were retrospectively reviewed and evaluated. RESULTS: The study included 14 patients. The average age of the patients was 35.7 (±14.35). The average stone size was 6.2 (±1.8) mm. Analgesic treatment and MET for distal ureteral stones were begun in 11 (78.6%) of the patients. Pain control was achieved in nine patients (64.2%) with analgesic treatment and MET, and the stone was removed without invasive intervention. Surgical intervention was performed in a total of five patients (35.7%). CONCLUSION: In most COVID-19 infected patients with renal colic and a distal ureteral stone, results can be obtained using MET. Patients with a distal ureteral stone and persistent renal colic can be safely and effectively treated by endoscopic ureteral stone treatment after taking necessary precautions. Prospective, randomised, and controlled studies are required on this subject.

The Effect of the Presence of Lower Urinary System Symptoms on the Prognosis of COVID-19: Preliminary Results of a Prospective Study.

PURPOSE: To investigate the effectiveness of benign prostatic hyperplasia (BPH)-related lower urinary tract symptoms (LUTS), which occur as a natural result of aging and androgen exposure, in predicting disease prognosis in male patients diagnosed with COVID-19. METHODS: The study was planned prospectively. The study included 63 male patients over 40 years of age diagnosed with COVID-19. The patients were diagnosed with COVID-19 based on the results of reverse transcription polymerase chain reaction tests of oropharyngeal and nasopharyngeal swabs obtained as per the World Health Organization guidelines. The presence of LUTS was assessed by the International Prostate Symptom Score (I-PSS), a subjective assessment, and the I-PSS was filled for the patients included in the study. The patients were divided into three groups based on their scores in the I-PSS survey: group 1: mild (0-7), group 2: moderate (8-19), and group 3: severe (20-35). The data of all three groups were statistically analyzed. RESULTS: In the assessment performed between the groups, it was identified that for patients in group 3, the length of hospital stay was longer, intensive care requirement was more frequent, and their mortality rates were numerically higher. In the evaluation made regarding the time to intensive care admittance, this was identified to be the shortest in group 3. CONCLUSION: As a result of our study, we think that in patients with COVID-19, BPH-related LUTS can guide clinicians in predicting prognosis.

The evaluation of prostate lesions with IVIM DWI and MR perfusion parameters at 3T MRI.

PURPOSE: The purpose of our study was to analyze the difference between IVIM DWI and perfusion parameters of malignant lesions and benign lesions-normal prostate tissue. METHODS: This prospective study included 31 patients who had multiparametric prostate MRI with IVIM DWI due to elevated prostate-specific antigen level and clinical suspicion between February 2015 and September 2016. RESULTS: For peripheral zone, the mean values of Ktrans, Kep, iAUC, χ2 and f were significantly higher in malignant lesions, and the mean values of Dt were significantly lower in malignant lesions (p 0.00, p 0.02, p 0.00, p 0.02 and p 0.00, respectively). For transitional zone, the mean values of Ktrans, Ve, iAUC, χ2 and f were significantly higher in malignant lesions, and the mean values of Dp and Dt were significantly lower in malignant lesions (p 0.00, p 0.00, p 0.00, p 0.00, p 0.00, p 0.02 and p 0.00, respectively). For whole prostate gland, the mean values of Ktrans, Kep, Ve, iAUC, χ2 and f were significantly higher in malignant lesions, and the mean values of Dp and Dt were significantly lower in malignant lesions (p 0.00, p 0.03, p 0.00, p 0.00, p 0.00, p 0.01, p 0.04 and p 0.00, respectively). CONCLUSIONS: Restricted diffusion-pseudodiffusion and increased perfusion parameters are important to differentiate prostate cancer from benign pathologies. It is also important to keep in mind that transitional zone and peripheral zone tumors may have different perfusion and diffusion parameters. Future studies are needed to confirm our findings.

Acute urinary retention after venlafaxine use.

We describe a case of lower urinary system symptoms (LUSSs) and acute urinary retention that developed after treatment with a low dose of venlafaxine. A 48-year-old male patient was admitted to our clinic because of difficulty urinating, an intermittent stream, and trickling at the end of urination, together with urinary retention that had started about 45 days ago. The patient had been taking venlafaxine for the previous 6 months. The drug had been prescribed by the psychiatry department for a diagnosis of major depression, and the dose had been increased from 75 mg/day to 150 mg/day 1.5 months earlier. The patients' symptoms were thought to be related to venlafaxine, and the symptoms disappeared completely after venlafaxine was replaced with agomelatine. We concluded that the LUSSs and urinary retention were due to the venlafaxine treatment.

Micropercutaneous Nephrolithotomy in the Management of Bilateral Renal Stones in a 7-Month-Old Infant: The Youngest Case in the Literature.

During infancy, the renal parenchyma and pelvicalyceal system are relatively fragile. Therefore, percutaneous nephrolithotomy for the management of renal stones in this age group is a challenging procedure for urologists. Herein, we present the uneventful management of bilateral renal stones using micropercutaneous nephrolithotomy (microperc) administered to a 7-month-old infant with recurrent urinary tract infections. In this paper, the advantages and disadvantages of the microperc procedure are discussed. As far as we know, our patient is the youngest case in whom the microperc procedure has been performed.

Challenges in treatment and diagnosis of forgotten/encrusted double-J ureteral stents: the largest single-center experience.

PURPOSE: We aimed to evaluate the effectiveness of the endourologic management of forgotten and/or encrusted ureteral stents together with our single-center experience. MATERIALS AND METHODS: Fifty-four patients with forgotten double-J ureteral stents were treated in our center between January 2008 and March 2014. Encrustation and the related stone burdens were estimated by using computerized tomography and kidney-ureter-bladder radiography. The management method was chosen based on the stone burden or clinical and radiological findings. RESULTS: Fifty-four patients, 39 males and 15 females, were included in the study. The average age of the patients was 38.2 ± 25.06 (2-86) years. The average indwelling time of the ureteral stents was 22.6 ± 30.3 (6-144) months. Six of the patients with forgotten stents had solitary kidneys. The double-J stent (DJS) was fragmented in four (7.4%) patients. A urinary system infection was present in 15 (27.7%) of the patients. The ureteral stents and related stones were successfully removed without any complications by combined endourologic techniques to achieve a stone-free state in all patients except for patient with 110 months of forgotten stent time in whom nephrectomy was performed for a nonfunctioning kidney related to the forgotten stent. CONCLUSIONS: Forgotten/encrusted DJS may lead to complications in a range of urinary system infections, up to a loss of renal function. They can be safely and successfully removed, and the renal function can be preserved by endourologic techniques, starting with the least invasive procedures in centers highly experienced.

Preputial bacterial colonisation in uncircumcised male children: Is it related to phimosis?

OBJECTIVE: To evaluate the presence of uropathogens in the periurethral skin and the effect of phimosis on bacterial colonisation. METHODS: The observational cohort study was conducted in Samsun Research and Training Hospital, Samsun, Turkey from June to December, 2014, and comprised patients undergoing circumcision. Before circumcision, all children were examined in the operating room and the presence of phimosis was recorded. All patients had circumcision performed by the same surgical team under general anaesthesia. Before the procedure, samples were taken from preputial skin of all patients by swab before cleansing with polyvidone-iodine. The samples were inoculated on 5% sheep blood agar and eosin-methylene blue agar. RESULTS: The median age of the 117 children was 5 years (range: 1-12). Of the total, 19(16.2%) children had complete phimosis, and 72(61.5%) had partial phimosis. In all,91(77.7%) children had phimosis and 26(22.3%) had no phimosis. Of the 91 patients with different degrees of phimosis, 52(57.1%) had clinically significant uropathogenic bacterial colonisation >100,000 colony-forming units per millilitre [cfu/ml]). Of the 26 patients without phimosis, 13(50%) had clinically significant colonisation. Thus, there was no effect of the presence of phimosis on bacteria colonisation (p=0.655). CONCLUSIONS: Important uropathogens colonise the preputium in uncircumcised male children. There was no effect of phimosis on colonisation.

Incidence of bacterial colonisation after indwelling of double-J ureteral stent.

OBJECTIVE: To determine the bacterial colonisation after double-J stent use and the risk factors for bacteriuria linked to the stent. MATERIALS AND METHODS: A total of 102 patients (61 men and 41 women, mean age 47.5 ± 14.16) were examined. The stents were removed under aseptic conditions, and a urine culture was obtained before the removal of the stents. After the stents were removed, the upper, central and lower sections were separated, and washing water was sent through the stent. RESULTS: Bacterial colonisation was found in 29.4% (30 of 102) of the stents. The most frequently observed microorganisms were determined as staphylococcus, coagulase negative (8 of 30) and E. coli (5 of 30). The washing fluid used to clean the interior of the catheter produced pathogens in 8 patients (7.8%), and these pathogens were observed to be the same microorganisms that colonised the outside of the stent. There was no statistical difference between the patients with colonisation and those without in terms of age, gender, duration of stenting and reason for stent insertion. CONCLUSIONS: Though stent colonisation does not always entail symptomatic urinary tract infections, as shown in our study, the pathogens in the urine culture are the same as those colonising the stent, confirming the reality that colonisation is the main factor in these events. Additionally, according to our study, significant colonisation may be found in the first 3 weeks, contrary to the literature, causing us to consider that urinary tract infections may develop even in the early period.

Renoprotective effect of aliskiren on renal ischemia/reperfusion injury in rats: electron microscopy and molecular study.

PURPOSE: To determine the protective effect of aliskiren on ischemia-reperfusion (I/R) injury in a rat renal (I/R) model. METHODS: Rats were randomly divided into five groups: sham control group; sham control with aliskiren pretreatment; I/R group and I/R with two doses of aliskiren pretreatment. Rats were unilaterally nephrectomized and subjected to 45 min of renal pedicle occlusion followed by 24 h reperfusion. Aliskiren (50 and 100 mg/kg) was administered orally by gavage 24 and 1 h prior to ischemia. After 24 h reperfusion, kidney samples were taken for the determination of malondialdehyde (MDA) level, superoxide dismutase (SOD), glutathione (GSH) activity and histological evaluation. The level of serum creatinine (SCR) and blood urea nitrogen (BUN), renin and angiotensin II (AT-2) was measured in serum samples. RESULTS: Kidneys from I/R groups showed significant increase in MDA level and significant decrease in GSH, and SOD activity. IL-1ß, iNOS and NFkB gene expression significantly increased in the I/R groups in the rat kidney tissue. Aliskiren treatment showed a significant down-regulatory effect on IL-1ß, iNOS and NFkB mRNA expression. Compared with the sham group, SCR and BUN, renin and AT-2 were significantly increased in the I/R rats, accompanied by histopathological damage to the kidney. CONCLUSION: Pretreatment with aliskiren ameliorated I/R-induced renal injury through decreasing nitric oxide and AT-2 levels and by the reduction of injury induced by I/R injury and ameliorated renal histopathological molecular and biochemical changes.

Feasibility study of CT perfusion imaging for prostate carcinoma.

OBJECTIVE: The aim of this feasibility study was to obtain initial data with which to assess the efficiency of perfusion CT imaging (CTpI) and to compare this with magnetic resonance imaging (MRI) in the diagnosis of prostate carcinoma. MATERIALS AND METHODS: This prospective study involved 25 patients with prostate carcinoma undergoing MRI and CTpI. All analyses were performed on T2-weighted images (T2WI), apparent diffusion coefficient (ADC) maps, diffusion-weighted images (DWI) and CTp images. We compared the performance of T2WI combined with DWI and CTp alone. The study was approved by the local ethics committee, and written informed consent was obtained from all patients. RESULTS: Tumours were present in 87 areas according to the histopathological results. The diagnostic performance of the T2WI+DWI+CTpI combination was significantly better than that of T2WI alone for prostate carcinoma (P < 0.001). The diagnostic value of CTpI was similar to that of T2WI+DWI in combination. There were statistically significant differences in the blood flow and permeability surface values between prostate carcinoma and background prostate on CTp images. CONCLUSION: CTp may be a valuable tool for detecting prostate carcinoma and may be preferred in cases where MRI is contraindicated. If this technique is combined with T2WI and DWI, its diagnostic value is enhanced. KEY POINTS: Perfusion CT is a helpful technique for prostate carcinoma diagnosis. •Colour maps allow easy and rapid visual assessment of the functional changes. Colour maps of prostate carcinoma provide information about in vivo tumoral vascularity. CTp images may be added into routine radiological examinations. CTp provides guidance for histopathological correlation if biopsy is scheduled.

Holmium laser lithotripsy with semi-rigid ureteroscopy: a first-choice treatment for impacted ureteral stones in children?

BACKGROUND: We aimed to assess the effectiveness of semi-rigid ureteroscopy and holmium laser lithotripsy in the treatment of impacted ureteral stones in children. MATERIAL/METHODS: We evaluated a total of 32 children under the age of 18 years treated with ureteroscopic holmium laser lithotripsy for impacted ureteral stones between January 2005 and July 2013. Their stone-free state was defined as the absence of any residual stone on radiologic evaluation performed 4 weeks postoperatively. Complications were evaluated according to the modified Clavien classification. RESULTS: The mean patient age was 9.5±5.1 years (range 1-18 years). Seven (21.8%) of the stones were located in the proximal ureter, 9 (28.2%) were in the mid-ureter, and 16 (50%) were in the distal ureter. The mean stone size was calculated as being 10.46±3.8 mm2 (range 5-20). The stone-free rate was 93.75% (30/32 patients) following primary URS. Additional treatment was required for only 2 (6.25%) of the patients. After the procedure, a D-J stent was placed in all the patients. The total complication rate was 15.6% (5 patients). The 10 total complications in these 5 patients were 5 (15.6%) Grade I, 1 (3.1%) Grade II, 2 (6.25%) Grade IIIa, and 2 (6.25%) Grade IIIb. The mean follow-up period was 16.5 months (range 3-55). CONCLUSIONS: For the treatment of impacted ureteral stones in children, holmium laser lithotripsy with semi-rigid ureteroscopy, with its low retreatment requirement and acceptable complication rates, is an effective and reliable method in experienced and skilled hands as a first-choice treatment approach.

Giant isolated renal cyst hydatid: From diagnosis to treatment.

Hydatid cyst disease is a parasitic infestation caused by Echinococcus granulosus. Renal involvement is rarely seen as 2-4% of all cases. Rarely renal involvement is isolated whereas commonly it accompanies involvement of other organs. We aimed to present a 30-year-old male patient with renal involvement reaching a giant size and undiagnosed in another center.

Renal epithelioid angiomyolipoma mimicking urothelial carcinoma of the upper urinary tract.

Epithelioid angiomyolipoma is a rare mesenchymal tumor arising mainly in the kidney that can potentially behave aggressively. Epithelioid angiomyolipoma can often resemble sarcomatoid renal cell carcinoma, high grade renal carcinoma or sarcoma. Its similarity to renal cell carcinoma has been emphasized in most of the cases reported in literature. With the purpose of contributing to the awareness of this similarity, a 32-year-old female patient with renal epitelioid angiomyolipoma in the left kidney which radiologically mimicked urothelial cell carcinoma of the upper urinary tract is presented.

Ureteroscopy and holmium laser lithotripsy: is this procedure safe in pregnant women with ureteral stones at different locations?

OBJECTIVES: The aim of this study was to assess the safety and effectiveness of ureteroscopy and Holmium: Yttrium-Aluminum-Garnet lithotripsy for the treatment of ureteral stones with different localizations in symptomatic pregnant women. METHODS: A retrospective analysis was performed on 19 pregnant patients referred to our center between January 2005 and December 2012 with symptomatic hydronephrosis requiring surgical intervention. 7.5 F and 9.5 F semirigid ureterorenoscopy with Holmium laser lithotripsy was used for treatment in all patients. Complications were stratified according to modified Clavien criteria. RESULTS: The mean age of patients was 25.4 (18-41) years, and the mean gestation duration was 24.8 (7-33) weeks. Six cases (31.5%) had a history of stone. Solitary kidney secondary to previous nephrectomy was observed in 2 patients and 1 patient had a hypoplastic kidney. Abdominal ultrasonography was used as the main diagnostic tool. Mean stone size was 9.2 mm (6-13). The location of the stones was the lower, middle, and upper ureter in 8 (42.1%), 5 (26.3%) and 6 (31.5%) cases, respectively. All stones were fragmented with Holmium laser lithotripsy. Of the 19 patients, 11 (57.8%) required double J stent insertion peroperatively. Intraoperative urological and obstetric complications were not observed. Postoperatively two complications were noted. According to Clavien criteria a complication was level 1, and the other was level 2. CONCLUSIONS: For treatment of pregnant women with symptomatic ureteral stones in every location, Holmium laser lithotripsy with a semirigid ureteroscopy can be used as judicious treatment. This approach is effective and safe with an acceptable complication rate.

The forgotten ureteral stent in children: from diagnosis to treatment.

PURPOSE: We conducted a multicenter pediatric study of ureteral stents unintentionally left in situ. MATERIALS AND METHODS: A total of 22 patients with encrusted Double-J® ureteral stents unintentionally left in situ were treated at 4 centers between January 2007 and March 2012. Stone burdens were estimated using plain radiography and computerized tomography. Treatment decision was made based on clinical and radiological findings or stone burden. RESULTS: Nine girls and 13 boys with a mean age of 9.5 years (range 2 to 16) were analyzed. Mean indwelling time of ureteral stent was 21.7 months (range 6 to 60). Stents were inserted for the indication of urolithiasis (17 patients) and reconstructive urological intervention (5). In 2 patients stents had been placed bilaterally. Mean stent stone burden was 184 mm(2) on plain radiography and 247 mm(2) on computerized tomography, a difference that was statistically significant (p = 0.002). Shock wave lithotripsy was done in 6 cases. Endoscopic procedures were performed in all patients, including ureteroscopy in 8, simple stent removal in 7, endoscopic cystolithotripsy in 6, percutaneous nephrolithotomy in 5, retrograde intrarenal surgery in 3 and percutaneous cystolithotripsy in 2. Surgical removal of each stent required a mean of 1.5 interventions and a mean hospital stay of 4.4 days. CONCLUSIONS: At experienced centers combined endourological techniques can achieve successful and safe management of forgotten stents even in the pediatric age group. Thus, routine preprocedural tomography is a must in children with forgotten ureteral stents.

Comparing the Effects of 2D and 3D Imaging Systems on Laparoscopic Pyeloplasty Outcomes in the Treatment of Adult Ureteropelvic Junction Obstruction.

Background: The aim of this study was to compare the efficacy, safety, and the clinical and perioperative outcomes of two-dimensional (2D) and three-dimensional (3D) laparoscopic imaging systems in adult patients undergoing laparoscopic pyeloplasty in our clinics due to ureteropelvic junction (UPJ) obstruction. Methods: A total of 46 adult patients who had undergone laparoscopic pyeloplasty due to UPJ obstruction were included in the study. Cases that had undergone the operation before January 2019 were retrospectively evaluated with the 2D imaging systems. Cases after that date were evaluated by using the 3D imaging systems, and the operative, perioperative, and postoperative findings of these patients were recorded prospectively. Patients who had undergone laparoscopic pyeloplasty were classified into two groups as the "2D group" and the "3D group." To standardize the preoperative findings, the cases that were operated by a single surgeon experienced in both 2D and 3D imaging systems were included in the study. The demographic characteristics and the clinical findings of the patients were compared between the groups. Results: A total of 41 patients were included in the study. The mean age was 27.7 ± 9.17 years. Among the patients, 23 (56.1%) were in the 2D group and 18 (43.9%) were in the 3D group. No statistically significant difference was observed between groups with regard to the demographic characteristics of the patients. According to the perioperative and postoperative findings of the patients, the duration of the operation was significantly shorter in the 3D group. Conclusion: The duration of the operation was significantly reduced in the 3D image-guided laparoscopic pyeloplasty in the treatment of UPJ obstruction of the adult, compared with 2D image-guided operations. The 3D imaging systems provide a better image quality, an important convenience in intraoperative saturation, and low rates of complication in laparoscopic pyeloplasty, and they may be used safely and effectively.

Comparison of Perioperative, Oncological, and Functional Outcomes of Three-Dimensional Versus Robot-Assisted Laparoscopic Radical Prostatectomy: A Preliminary Study.

Background: Radical prostatectomy (RP) is the first-line treatment modality for prostate cancer and can be performed using retropubic or minimally invasive techniques. New technologies such as the da Vinci robotic system and three-dimensional (3D) laparoscopic imaging system have been developed to overcome the challenges of conventional laparoscopy. This study aimed to compare the perioperative, oncological, and functional outcomes of robot-assisted laparoscopic RP (RALP) and 3D laparoscopic RP (3D LRP). Materials and Methods: The study was approved by the local ethics committee and included 65 patients (38 RALP, 27 3D LRP) who underwent RP with the diagnosis of localized prostate cancer between May 2019 and January 2020. All demographic, clinical, perioperative, pathological, and postoperative variables were recorded. Results: There was no statistically significant difference between the two groups in terms of preoperative patient characteristics. The mean operative times of the RALP and 3D LRP groups were 135.74 ± 11.51 and 165.37 ± 15.86 minutes, respectively, with a statistically significant difference between the two groups (P = .001). The mean estimated blood loss was 237 ± 71 mL in the RALP group and 257 ± 54 mL in the 3D LRP group, with no statistically significant difference between the two groups (P = .236). In the 6 months of follow-up, there was no statistically significant difference between the two groups in terms of biochemical recurrence, continence, and potency. Conclusion: RALP and 3D LRP have similar perioperative, short-term oncological and functional outcomes other than the operative time. There is a need for prospective, randomized studies with larger populations evaluating long-term oncological and functional outcomes.

Desires and attitudes of outpatients and physicians regarding the use of teleurology during the pandemic: a prospective survey study.

OBJECTIVE: It is not known to date how many patients admitted to urology outpatient clinics are willing to use telemedicine. We aimed to investigate knowledge levels and attitudes concerning the utilization of teleurology by patients applying to urology outpatient clinics. METHODS: This prospective multicentre survey study included 334 patients aged 18-65 years who applied to an urology outpatient clinics. The patients were asked questions about their attitudes and expectations regarding teleurology. Diseases were divided into seven subgroups due to the broad spectrum of diagnoses. Physicians' and patients' opinions on whether it was possible to manage the current medical condition via teleurology were recorded. RESULTS: 69.5% of patients stated that they had sufficient technical skills to use teleurology by themselves for medical examination. 55.4% of patients and 78.4% of physicians responded that the existing complaints were suitable for teleurology. Both patients and physicians deemed genital system diseases and urinary tract infections suitable for teleurology (p<0.001, p<0.001 for physicians, and p<0.001, p<0.001 for patients), whereas urine transport, storage and emptying disorders (p=0.003) and benign prostatic hyperplasia (p=0.029) were deemed to be suitable for teleurology only by the physicians. CONCLUSION: Our study shows that (i) the majority of our patient population has a telecommunications infrastructure suitable for teleurology, (ii) teleurology has aroused interest among patients, particularly during the pandemic period, and (iii) physicians and patients have high expectations that the problem can be solved with teleurology in suitable patients.
