RESUMEN
PURPOSE: To present a new protocol using antibiotic irrigation during lithotripsy in retrograde intrarenal surgery (RIRS) to provide sterility of the renal collecting system. METHODS: This prospective study included 102 patients who underwent RIRS between January 2022 and August 2023. The patients were examined in two groups as those who received antibiotic irrigation (n:51) and standard irrigation (n:51). In the antibiotic irrigation group, 80 mg of gentamicin was dissolved in normal saline in a 3 L irrigation pouch to obtain a 26.7 mg/L concentration. In the standard irrigation group, normal saline was used. Preoperative information, including age, sex, body mass index (BMI), ASA score, stone side, volume, and density, and the Seoul National University Renal Stone Complexity (S-ReSC) score. The groups were compared with respect to postoperative fever (> 38 °C), urinary tract infection (UTI), systemic inflammatory response syndrome (SIRS), infectious complications such as sepsis, and stone-free rate. RESULTS: No statistically significant difference was determined between the groups with respect to age, sex, BMI, ASA score, stone side, volume and density, and S-ReSC score (p > 0.05 for all). Statistically significant differences were determined between the groups with respect to postoperative fever (p = 0.05), SIRS (p = 0.05), and hospital length of stay (p = 0.05). Sepsis was observed in one patient in the standard irrigation group and in none of the antibiotic irrigation group. CONCLUSION: The reliability, efficacy, and utility of antibiotic irrigation during lithotripsy in RIRS were presented in this study as a new protocol for sterilization of the renal collecting system which will be able to reduce infectious complications.

OBJECTIVE: The aim of this study was to explore the criteria that can predict bladder cancer among the lesions that could not be differentiated from intravesical prostate protrusion (IPP) and to create a scoring system using these criteria. METHODS: A retrospective analysis was made of patients with an ultrasound report indicating lesions in the bladder neck, for which differentiation between bladder cancer and IPP could not be determined. A total of 174 patients diagnosed with bladder cancer (n=102) or benign prostate lesion (n=72) according to the biopsy results were enrolled in the study. Hemoglobin, prostate-specific antigen (PSA), prostate volume (PV), bladder wall thickness (BWT), lesion height (LH), and the ratio of lesion width to base (LW/B) were compared between the two groups. RESULTS: ROC analysis revealed an AUC value >0.7 for all factors, and the best cut-off value was identified for each factor. In the multivariate analysis, by determining a score for each factor according to the ORs, the BCa-IPP scoring system was developed to provide a total score in the range of minimum 0 and maximum 15. In the ROC analysis, the AUC value was 0.954 (95% CI: 0.923-0.986) for the BCa-IPP score. The best cut-off value was found to be 10, with sensitivity of 0.93 and specificity of 0.85. CONCLUSION: Using simple laboratory and ultrasound findings, the BCa-IPP scoring system was created, which was seen to have high predictive value and can be easily applied in the clinic. The BCa-IPP scoring system is a non-invasive test that can be successfully applied for the differentiation of bladder cancer from benign lesions.
RESUMEN
INTRODUCTION: The aim of the study was to investigate the value of prostate-specific antigen density (PSAD) and lesion diameter (LD) combination in prostate cancer (PCa) detection. METHODS: 181 patients who were detected to have prostate imaging-reporting and data system (PI-RADS) 3 lesions in mpMRI and underwent prostate biopsies were included in the study. Demographic, clinical, and pathological data of all patients were evaluated. The patients were divided into four groups according to PSAD and LD status (PSAD <0.15 ng/mL/cc + LD <1 cm, PSAD <0.15 ng/mL/cc + LD ≥1 cm, PSAD ≥0.15 ng/mL/cc + LD <1 cm, and PSAD ≥0.15 ng/mL/cc + LD ≥1 cm). Diagnostic ability for PCa and clinical significant PCa (csPCa) was evaluated by PSAD and LD. RESULTS: PSAD ≥0.15 ng/mL/cc (OR = 6; 95% Cl = 2.847-12.647; p < 0.001), LD ≥1 cm (OR = 7.341; 95% confidence interval [CI] = 2.91-18.52; p < 0.001), and combination of PSAD ≥0.15 ng/mL/cc and LD ≥1 cm (OR = 10.023; 95% CI = 4.32-23.252; p < 0.001) were associated with PCa detection rates. The most sensitivity, specificity, negative, and positive predictive values were found in PSAD ≥0.15 ng/mL/cc + LD ≥1 cm group for both PCa and csPCa detection (48.8%, 92%, 85.2%, and 65.6% for any PCa detection; 66.7%, 85.2%, 97.3%, and 24.2% for csPCa detection, respectively). CONCLUSION: The presence of PSAD ≥0.15 ng/mL/cc or LD ≥1 cm in mpMRI of patients with PI-RADS 3 lesions is associated significantly with the finding of PCa and particularly with the detection of csPCa.

PURPOSE: To evaluate the effect of the reverse Trendelenburg position in patients undergoing ureteroscopic lithotripsy for proximal ureteral stones. METHODS: The study included 167 patients who underwent ureteroscopic lithotripsy for proximal ureter stones between December 2020 and September 2022. The patients were randomly assigned to one of three groups: standard lithotomy (n:55), 10° reverse Trendelenburg (n:55), and 20° reverse Trendelenburg (n:57). Preoperative information, including age, sex, body mass index (BMI), previous shock wave lithotripsy (SWL), stone side, volume, and density, distance to the ureteropelvic junction (UPJ) of the stone, and hydronephrosis degree. Stone-free status was evaluated with computed tomography (CT) at 4 weeks postoperatively. The groups were compared in respect of stone migration, stone-free rate, use of flexible ureterorenoscope, operating time, postoperative length of stay in the hospital, and complications. RESULTS: No statistically significant difference was determined between the groups with respect to age, sex, BMI, previous SWL, stone side, volume and density, distance to the UPJ of the stone, and hydronephrosis degree (p > 0.05 for all). Statistically significant differences were determined between the groups with respect to stone migration (p = 0.001), stone-free rate (p < 0.001), use of flexible ureterorenoscope (p = 0.01), operating time (p < 0.001), hospital length of stay (p < 0.001), postoperative fever (p = 0.002), and total complications (p = 0.01). CONCLUSION: A new patient position is presented in this study, which can be used in ureteroscopic lithotripsy performed for proximal ureteral stones. The reverse Trendelenburg position constitutes a surgical method that can be used safely and successfully in the treatment of proximal ureteral stones. TRIAL REGISTRATION NUMBER: NCT04894058, 05/21/2021, Prospectively registered.

INTRODUCTION: The aim of the study was to determine the correlation between the dwelling time for a ureteral stent placed for passive dilation after impassable ureteroscopy and success and complications. METHODS: A retrospective evaluation was made of patients who underwent stent placement after impassable ureteroscopy and a repeat ureteroscopy due to kidney stones. A total of 161 patients were included in the study between 2015 and 2022. Demographic, clinical, preoperative, and perioperative data were collected. Logistic regression analyses were performed on the data showing a significant difference in the univariate analyses performed to determine the predictive factors of ureteroscopy after the stent dwelling period in terms of stone-free status and perioperative complications. RESULTS: Stone-free status was achieved in 110 (68.3%) of 161 patients, and perioperative complications were observed in 41 (25.4%). Factors that affected the stone-free status were determined as the dwelling time and the S-ReSC score, while factors affecting perioperative complications were the stent dwelling time and the operation time. The stone-free rates were observed to increase from 46.4% in the first 2 weeks to 72.9% after the 2nd week, an increase of 1.5-fold. Perioperative complications were determined at the rate of 17.5% during the first 5 weeks and increased 2.1-fold to 37.5% after the 5th week. CONCLUSION: It can be recommended that great care is taken during the stent dwelling period and ureteroscopy should be performed within 5 weeks (14-35 days) but no earlier than 2 weeks, so as not to affect the success of the procedure.

BACKGROUND: The aim of the present study is to investigate the efficiency of roflumilast and ibuprofen in an experimental rat testicular ischemia reperfusion injury model in the light of histological and biochemical data. METHODS: A total of 32 prepubertal male rats were randomly divided into four groups as G1: Control Group (testicular torsion/detorsion + saline (0.9% of 2 ml) was applied). G2: Sham Group only right scrotal incision was performed; G3: Ibuprofen Group (tes-ticular torsion/detorsion + ibuprofen administration); and G4 Roflumilast Group (testicular torsion/detorsion + roflumilast adminis-tration). Oxidative markers such as malondialdehyde (MDA), myeloperoxidase (MPO), total sulfhydryl (TSH), and nitrite (NO) levels as well as histopathological changes were analyzed. RESULTS: Tissue MPO, MDA, and NO levels were significantly higher and TSH levels significantly lower in control group compared to sham group (p<0.001). The histopathologic scores of drug groups (Groups 3 and 4) were significantly lower than group 1 (p<0.001). In comparison of Group 3 and Group 4 with each other, the mean values of MPO and MDA were statistically significantly lower in Group 4 (p<0.001). A higher mean value of TSH was found in Group 3 without statistically significance (p=0.32). There was also an insignificant decrease in mean NO values of Group 3 compared to Group 4 (p=0.44). In comparison of drug groups, Group 4 had statistically insignificant better scores. CONCLUSION: Our results indicate that administrating ibuprofen and roflumilast reduced testicular ischemia reperfusion injury in rat testis torsion model. In comparison, roflumilast is found to be more beneficial.

OBJECTIVES: To evaluate the impact of the presence and severity of urinary incontinence (UI) on pregnancy-related anxiety. STUDY DESIGN: This prospective case-control study included 160 pregnant women. Pregnant women with UI (n = 80) were compared with continent pregnant women (n = 80; control group) in terms of scores on the Incontinence Consultation Questionnaire-Short Form (ICIQ-SF) and the Pregnancy-related Anxiety Questionnaire-Revised 2 (PRAQ-R2) scale. Gynaecological examination was performed, and pelvic organ prolapse was diagnosed using the Pelvic Organ Prolapse Quantification system. UI was classified as stress UI (SUI), urge UI (UUI) or mixed UI (MUI). RESULTS: The total PRAQ-R2 score was significantly higher in all pregnant women with UI, as well as the UI subgroups, compared with the control group [mean ± standard deviation; 21.77 ± 8.1 (UI), 19.39 ± 6 (SUI), 20.13 ± 7.2 (UUI) and 28.1 ± 9.5 (MUI) vs 15.76 ± 5.9 (control group); p < 0.0001, p = 0.002, p = 0.012 and p < 0.0001, respectively). Significant positive correlation was found between the total ICIQ-SF and total PRAQ-R2 scores (r = 0.533; p < 0.0001). The score for the fear of giving birth domain in PRAQ-R2 was higher in women with SUI and MUI compared with the control group (9.5 ± 4 and 11.1 ± 2.6 vs 5.43 ± 2.4; p < 0.0001). Concern about own appearance was greater in the UUI and MUI groups compared with the control group (9.68 ± 4.5 and 7.8 ± 3.1 vs 4.85 ± 2.3; p < 0.0001). CONCLUSION: To the authors' knowledge, this is the first study to report the impact of the presence and severity of UI on pregnancy-related anxiety. The current findings show that anxiety may be an important psychosocial consequence of UI in pregnancy. This may lead to a clinical approach focusing on both the physical and psychological well-being of pregnant women with UI.

PURPOSE: To determine the nephroprotective effect of NAC and Montelukast Sodium administration against the development of renal damage associated with long warm renal ischemia. METHODS: Twenty-seven rats were randomly divided into 3 study groups, which received NAC, montelukast and placebo, and 3 rats were included in the sham-treated control group. Medications were given 3 days before the procedure. DMSA renal scintigraphy was performed before and after surgery. The right renal pedicle was occluded for 45 min to induce ischemia and then subjected to reperfusion for 6 h (I/R groups). RESULTS: On pathological examination, the mean pathological scores of the montelukast and NAC groups were significantly lower than those of the placebo group. (p <0.05). In biochemical examination, significant differences were found in all parameter levels between the placebo group and the montelukast and NAC groups. (p <0.05) When postoperative DMSA renal scintigraphy measurements and renal function levels were compared, significant differences were found between the montelukast and NAC groups and the placebo and sham groups. CONCLUSION: The administration of NAC and montelukast sodium was seen to have a nephroprotective effect against the development of renal damage associated with warm renal ischemia.

Ranolazine is a drug used in refractory chronic stable angina. In this study, it was aimed to evaluate the protective effect of ranolazine in a testis torsion model in light of objective biochemical and pathological data. A total of 24 pre-pubertal male Wistar albino rats were separated into three groups of 8 as the sham group, control group and ranolazine group. Testis torsion was applied for 3 hr to all the rats in Group Control and Group Ranolazine. In Group Control, 0.9% NaCl was applied 1 hr after the torsion. In Group Ranolazine, ranolazine 30 mg/kg was dissolved in a 0.9% NaCl solution and was administered intraperitoneally 1 hr after torsion. Histopathological evaluation was made using the Cosentino score. As a result of the objective biochemical and pathological criteria used in this study, this protective effect of ranolazine was observed in testis torsion. The results obtained in this study may suggest that ranolazine is a drug that could be applied after detorsion to patients diagnosed with torsion.

Urinary tract infections (UTIs) still represent a significant bother for women and result in high costs to the health system. Increasing antimicrobial resistance has stimulated interest in non-antibiotic prophylaxis of recurrent UTIs. Evidence shows that the microorganisms inhabit many sites of the body, including the urinary tract which has long been assumed to be sterile in healthy individuals, might have a role in maintaining urinary health. Studies of the urinary microbiota (UM) have identified remarkable differences between healthy populations and those with urologic diseases. The depletion of these organisms in women susceptible to UTIs raised the question of whether artificial supplementation of these microorganisms as probiotics could lower infection rates. In the literature, probiotic interventions were shown to have some efficacy in the treatment and prevention of urogenital infections. Despite previous controversy regarding the use of probiotics, as treatment for UTIs, there are increasing signs that it may be possible to use them as a first step in regulating the UM so as to reduce the risk of or as a treatment for certain urinary diseases. However, further future clinical trials, involving large numbers of patients, will be mandatory to achieve definite evidence of the preventive and curative role of probiotics in UTIs. Details about correct formulations in terms of amount of bacteria, viability and associated growth factors, will be required in order to standardize the administration schedule and achieve homogeneous and comparable results on selected patients.
RESUMEN
PURPOSE: Comparison of efficiency and reliability of percutaneous nephrolithotomy (PNL) and retrograde intrarenal surgery (RIRS) in treatment of multicalyceal and multiple renal stones in the same renal unit. MATERIALS AND METHODS: Between 2011 and 2015, records of patients who underwent surgery for renal stone were retrospectively reviewed. Patients who had multiple stones located in different calices in the same renal unit were included. The patients that underwent PNL and RIRS were defined as Group I and Group II, respectively. Patient criteria (age,sex); the stone characteristics; time of procedure, fluoroscopy and hospitalization; stone-free and complication rates of groups were evaluated between the treatment groups. RESULT: There were no significant differences in terms of age, gender, BMI, laterality, number of stones, number of stone localization, hounsfield units and surface area characteristics of the stone between the PNL (n = 47) and RIRS (n = 35) groups (P = .558, P = .278, P = .375, P = 0.051, P = .053, P = .064, P = .642, P = .080, respectively). Stone free rate was 59.6% (n=28) in PNL, and 88.6% (n=31) in RIRS (P=.004). 1st or 2nd degree complications according to Modified Clavien Classification developed in 10 patients (21.3%) in Group I and 1 patient (2.9%) in Group II (P = .015). The 3A or 3B complications were similar in groups (P = .077). Time of procedure, fluoroscopy and hospitalization were significantly lower in Group II (P < .001, P < .001 and P < .001, respectively). CONCLUSION: RIRS is more effective and more reliable procedure than PNL with higher stone-free and lower complication rates in treatment of multicalyceal and multiple stone in the same renal unit.

ABSTRACT Objective: To investigate the effect of papaverine and alprostadil on testicular torsion-detorsion injury in rats. Materials and Methods: A total of 40 male Wistar-Albino rats were used in this study. Four hours of right testicular torsion was applied to each group, excluding sham oper- ated group. The torsion-detorsion (T/D), T/D + papaverine and T/D + alprostadil groups received saline, papaverine and alprostadil at the same time as surgical detorsion, respectively. At 14 days after the surgical detorsion, ischaemic changes and the degree of damage were evaluated with Cosentino scoring and the Johnson tubular biopsy score (JTBS). Results: JTBS was determined as 8.8±2.7 in the Sham group, 5.08±1.9 in the T/D+papaverine group, 5.29±2.3 in the T/D +alprostadil group and 2.86±1.9 in the TD group. The JTBS was determined to be statistically significantly high in both the T/D + papaverine group and the T/D + alprostadil group compared to the T/D group (p=0.01, p=0.009). In the T/D + papaverine group, 3 (43%) testes were classified as Cosentino 2, 3 (43%) as Cosentino 3 and 1 (14%) as Cosentino 4. In the T/D +alprostadil group, 5 (50 %) testes were classified as Cosentino 2, 3 (30 %) as Cosentino 3 and 2 (20%) as Cosentino 4. Conclusion: The present study indicated that spermatic cord administration of alprostadil and papaverine showed a protective effect against ischemia/reperfusion injury after right-side testes torsion and histological changes were decreased after testicular ischemia reperfusion injury.

PURPOSE: To investigate whether use of dutasteride, a 5-alpha reductase inhibitor, for at least four weeks preoperatively affected the blood loss during open prostatectomy (OP). MATERIALS AND METHODS: Retrospective analysis was made of the data of 110 patients who had undergone OP. Group I comprised 50 patients that used dutasteride for 4 weeks preoperatively, and Group II comprised 60 patients that did not use the drug. The groups were compared in respect of age, total prostate specific antigen (TPSA) levels, prostate volumes, preoperative hemoglobin (Hgb) and hematocrit (Hct) levels, postoperative reduction of Hgb and Hct, percentage reduction in Hgb and Hct, and the administration of postoperative blood products. RESULTS: No differences were determined between the two groups in respect of prostate volumes, TPSA, preoperative Hgb and Hct levels (P = .813, P = .978, P = .422, P =.183, respectively). Postoperative Hgb reduction was 2.19 ± 1.36 g/dL in Group I, and 2.5 ± 1.47 g/dL in Group II (P = .260). Hgb reduction was calculated as 16.4 ± 9.7% in Group I and 17.6 ± 9.7% in Group II (P = .505). Reductions in Hct were 5.8 ± 3.7% in Group I, and 7.3 ± 4.4% in Group II, and percent reductions were 14.8 ± 9.4% in Group I and 17.3 ± 10.2% in Group II (P = .068, P = .182, respectively). CONCLUSION: The use of dutasteride before OP did not affect blood loss during surgery, therefore surgery should not be delayed for the administration of dutasteride to patients.

PURPOSE: To investigate the effect of respiratory induced kidney mobility on success of shock wave lithotripsy (SWL) with an electrohydraulic lithotripter. MATERIALS AND METHODS: Between May 2013 and April 2015, 158 patients underwent SWL treatment for kidney stones with an electrohydraulic lithotripter. The exclusion criteria were presence of a known metabolic disease (such as cystinuria), non-opaque stones, need for focusing with ultrasonography, abnormal habitus, urinary tract abnormalities, and inability to tolerate SWL until the end of the procedure. Stones greater than 20 mm, and lower pole stones were also excluded. The movement of the kidneys were measured with fluoroscopy guidance. RESULTS: The procedure was successful in 66.7% of the males, and 56.9% of the females. The mean stone size was 11 ± 3 mm in the successful group, and it was 14 ± 4 mm in the unsuccessful group. The mean stone mobility rate was 32 ± 10 in the successful group and 40 ± 11 in the unsuccessful group. Multivariate analysis showed that stone size and kidney mobility affected the success rate significantly, however Hounsfield Unit (HU) did not. CONCLUSION: The current study shows the significant effect of kidney motion on the success of SWL. Further studies with different lithotripters are needed to determine the significance of kidney mobility.

OBJECTIVE: We aimed to compare the success and complications of ultra-mini percutaneous nephrolithotomy and micro-percutaneous nephrolithotomy techniques. METHODS: We retrospectively analyzed data from 74 patients. Moderate-size stones were included in the study. RESULTS: Forty-two patients were included in MPNL, and 32 patients were included in UPNL groups. Among our patient cohort, 42 (56.7%)were males, and 32 (43.3%) were females. The mean age of the patients was 40±13.2 years in the MPNL group, and the mean age of the patients was 42±14.1 years in the UPNL group. The mean stone size was 17±3.2 mm in the MPNL group and 16.4±3.7 mm in the UPNL group. The stonefree rates were 88.1% (37/42) and 90.6% (29/32)in the MPNL and UPNL groups, respectively; there was no statically significant difference between the groups. The mean hospital stay was 1.4±0.23 days in the MPNL group and 1.1±0.12 day in the UPNL group. CONCLUSIONS: Two techniques have similar success and complication rates, and both may be preferred particularly in moderate-size stones. Our experience supports that our UPNL technique is safe and effective using with a standard ureteroscope.

OBJECTIVE: We aimed to compare the success and complications of ultra-mini percutaneous nephrolithotomy and micro-percutaneous nephrolithotomy techniques. METHODS: We retrospectively analyzed data from 74 patients. Moderate-size stones were included in the study. RESULTS: Forty-two patients were included in MPNL, and 32 patients were included in UPNL groups. Among our patient cohort, 42 (56.7%) were males, and 32 (43.3%) were females. The mean age of the patients was 40±13.2 years in the MPNL group, and the mean age of the patients was 42±14.1 years in the UPNL group. The mean stone size was 17±3.2 mm in the MPNL group and 16.4±3.7 mm in the UPNL group. The stonefree rates were 88.1% (37/42) and 90.6% (29/32) in the MPNL and UPNL groups, respectively; there was no statically significant difference between the groups. The mean hospital stay was 1.4±0.23 days in the MPNL group and 1.1±0.12 day in the UPNL group. CONCLUSIONS: Two techniques have similar success and complication rates, and both may be preferred particularly in moderate-size stones. Our experience supports that our UPNL technique is safe and effective using with a standard ureteroscope
OBJETIVO: Comparar las tasas de éxito y las complicaciones de las técnicas ultra-mini nefrolitotomia percutánea (UNLP) y micro Nefrolitotomía percutánea (MNLP). MÉTODOS: Analizamos retrospectivamente los datos de 74 pacientes. Se incluyeron en el estudio litiasis de tamaño moderado. RESULTADOS: Cuarenta y dos pacientes se incluyeron en el grupo de MNLP y 32 pacientes en el de UNLP. En nuestra cohorte de pacientes, 42 (56,7%) eran varones y 32 (43,3%) mujeres. La edad media de los pacientes fue de 40±13,2 años en el grupo de MNLP y 42±14,1 años en el grupo de UNLP. El tamaño medio de la litiasis fue de 17±3,2 mm en el grupo de MNLP y 16,4±3,7 mm en el grupo de UNLP. Las tasas de pacientes libres de litiasis fueron del 88,1% (37/42) y 90,6% (29/32) en los grupos de MNLP y UNLP, respectivamente; no había diferencias estadísticamente significativas entre los grupos. La estancia hospitalaria media fue de 1,4±0,23 días en el grupo de MNLP y 1,1±0,12 días en el de UNLP. CONCLUSIONES: Las dos técnicas tienen tasas de éxito y de complicaciones similares, y ambas pueden ser las preferidas para litiasis de tamaño moderado. Nuestra experiencia apoya que nuestra técnica de UNLP es segura y efectiva utilizando un ureteroscopio estándar

AIM: We aimed to compare the 18 and 16-Gauge (G) needles used in transrectal ultrasonography (TRUS)-guided needle biopsy for cancer detection rates and complications using the Clavien Scoring System. MATERIALS AND METHODS: The 80 patients who were included in the study were randomized and divided into two groups. Group 1 (n = 36) had a TRUS-guided prostate biopsy with an 18G needle and Group 2 had a 16G needle (n = 44). The hematuria, bleeding assessment, and infection events were evaluated on a daily basis. These complications were graded according to the Clavien Scoring. RESULTS: In Group 1, only five (13%) patients were diagnosed with prostate cancer, and three patients were reported to have atypical small acinar proliferation (ASAP). In Group 2, 16 (36%) patients were diagnosed with prostate cancer and one patient was reported to have ASAP. The difference in the prostate cancer detection rate between the groups was statistically significant. According to the Clavien grading system, the complications were at the Grade 1 level in 25 people in Group 1 in 29 people in Group 2. Grade 2 level complications were not observed in either group. While one person was Grade 3 in Group 1, two people in Group 2 had this rate. There were no significant differences between the groups. CONCLUSIONS: We found that cancer detection rate increased by increasing the thickness of the needle used in TRUS-guided prostate biopsy without any increase in the complications.
RESUMEN
INTRODUCTION: The developments in hypospadias surgical techniques and materials are intended to improve surgery outcomes and patient comfort. The aim of this study is to determine the effect of the Zaontz urethral stent (ZUS) (Cook Medical) on patient comfort and surgical success rates in children undergoing hypospadias surgery. METHODS: A feeding tube was used to repair 46 cases of primary distal hypospadias, and ZUS (6F, 8F, and 10F in diameter) was used to repair to 31 cases of primary distal hypospadias between December 2009 and June 2011 in our clinic. ZUS was compared with the feeding tube in terms of surgical success rates and patient comfort in assessments made during postoperative periods. RESULTS: The patients with ZUS were followed with a stent for seven days postoperatively, as were the patients with the feeding tube. There was no statistical difference between the two groups in terms of fistula formation (p>0.05). Patient comfort was evaluated by the Face, Legs, Activity, Cry, Consolability (FLACC) scale on the first and third postoperative days, and a statistically significant difference was observed in favour of ZUS on the third postoperative day (p<0.05). CONCLUSIONS: Compared with a feeding tube in hypospadias repair, ZUS does not make any contribution to the urinary fistula rates. However, ZUS may have an advantage in terms of patient comfort in the postoperative followup. On the other hand, the small number of patients and the high price of the ZUS were the most important limitations. Prospective, randomized trials are needed to assess efficacy and cost.
