Abstract Purpose The aim of this study is to evaluate the outcomes of retrograde intra renal surgery (RIRS) in the setting of large or multiple stones in children (15 mm, or both. Outcomes included stone free rate (SFR) and complications within 30 days. Results In total, 344 patients were included with 197 and 147 in Groups 1 and 2, respectively. Ureteric access sheaths were more frequently used in Group 2 (39.5% vs. 56.8%, p = 0.021). The operation time was significantly longer in Group 2 (p

Objective: The aim of this study was to investigate whether urinary glycosaminoglycans (GAG) levels reflect clinical status in men with lower urinary tract symptoms and if they could be used as a marker in management of overactive bladder (OAB). Methods: A total of 34 patients were recruited who were admitted with LUTS and diagnosed as having clinically bladder outlet obstruction (BOO) due to prostate enlargement. These newly diagnosed, never treated patients underwent routine investigation, consisting of history, physical examination, PSA, ultrasound, uroflowmetry, assessment of symptoms scored by both International Prostate Symptom Score (IPSS) and Marmara- Overactive Bladder Questionnaire (M-OBQ). The patients were divided into two groups as those with an initial M-OBQ score < 12 (group 1) and ≥ 13 (group 2). Alfa blocker was initiated in eligible patients. Further evaluations included prostate volume measurement, pre- and post-treatment urinary GAG levels, IPSS and M-QAOB values and maximum urine flow rate (Qmax). Results: Before treatment, urinary GAG level was 21.5 mg/gCr (6.1-45.5) in Group 1, and 23.35 mg/gCr (15.6-32.6) in Group 2 (p =0.845). After the treatment, the GAG level in Group 1 and Group 2 were found to be 19.8 mg/gCr (7.4-70.5) and 18 (7.6- 41.7), respectively (p = 0.511). No difference in GAG levels was found in subgroup analysis for patients with or without OAB. Conclusions: In recent years, there have been many studies investigating the relationship between LUTS and urinary markers. However, in our prospective study, no relationship was found between pre- and post- treatment urinary GAG levels in patients with LUTS with or without OAB.

Aim: The voiding diary (VD) yields crucial insights into voiding volumes (VV), voiding frequency (VF), and management habits in children with lower urinary tract (LUT) dysfunction. It is recommended to be conducted for a minimum of 2 days. Nevertheless, certain studies have indicated similarities in voided volumes between days in a three-day VD. This study aims to compare VV and VF values across days based on bladder capacity and symptom scores. Materials and Methods: Children who applied to the pediatric urology clinic due to LUT symptoms between 2022 and 2023 were included in the study. Retrospective evaluation was conducted on the records. Children with neurological deficits and incomplete data were excluded from the study. All children were assessed following the guidelines of ICCS and EUA and underwent a 3-day voiding diary. Mean VV and VF values of the whole group for each day were compared and subgroup analyzes were performed in terms of gender, Voiding Dysfunction Symptom Score (VDSS), bladder capacity (BC), and diagnoses. Results: A total of 109 (53 girls (48.6%), 56 boys (51.4%)) children with a median age of 8 (3-17) were included in the study. 77 (70.6%) children were diagnosed with overactive bladder, 8 (7.4%) with dysfunctional voiding, and 24 (22%) with monosymptomatic enuresis nocturne. The mean VVs between days were similar in the whole group (p = 0.759). Moreover, the mean VV of the first day was similar to the average of both the first two days and the three days (p = 0.021, p = 0.490). Also, the maximum and minimum VVs were similar between days (p = 0.942, p = 0.160, respectively). In subgroup analyses based on gender, bladder capacity, and symptom score, mean VV was also found to be similar. VF values were found to be significantly different between days. There was also a difference between VF values in children with VDSS > 8.5 (p = 0.012) and BC/EBC (%) > 65 (p = 0.030). In subgroup analysis for diagnoses, mean and maximum VV and VF were similar between the groups, except for VF (p = 0.026) in OAB. Conclusion: While the voided volumes of children with non-neurogenic LUT dysfunctions appear to be consistent across the days of the VD, variations in VF might arise, especially among children with a VDSS of > 8.5 and normal bladder capacity. As a result, we believe that using a VD spanning at least two days could enhance diagnostic accuracy and help prevent unnecessary treatment.

Objective: To evaluate the outcomes of flouroscopy-free retrograde intrarenal surgery (ffRIRS) and to investigate the factors that may affect stone-free rate. Materials and methods: The charts of patients who underwent ffRIRS between January 2017 and August 2019 were reviewed retrospectively. Patients with missing preoperative imaging and patients with kidney anomalies were excluded from the study. Age, gender, stone size, stone localization, stone density, laterality, operation time, stone-free rate, complications and auxiliary procedures were recorded and analyzed. Results: Study group involved 44 (43.1%) female and 58 (56.8%) male patients. Stone-free rate in a single-session ffRIRS were found to be correlated with stone localization (p = 0.003), stone volume (p = 0.004), and stone density (p = 0.009) but not with age (p = 0.950). Patients with multiple calyceal stones and a stone burden over 520 mm3 were found to be less stone-free. The complication rate in female gender (n = 7) was significantly higher compared to male (n = 1) (p = 0.011). No major complications such as ureteral injury or avulsion were observed. Overall, 13 patients (12.7%) needed auxiliary procedures. The operation time seemed to be affected by stone size and gender (p = 0.005; p = 0.044, respectively). Conclusions: Stone-free rate in ffRIRS were found to be affected by stone density, size, and localization. Patients with multiple caliceal stones and high stone burden (< 520 mm3) have been found to have low stone-free rate, so one can speculate that having fluoroscopy assistance in RIRS might help us to improve surgical success.

Aim: To date, various molecules have been investigated to reduce the effect of renal ischemia/reperfusion (I/R) injury. However, none have yet led to clinical use. The present study aimed to investigate the protective effect of cordycepin (C) on renal I/R injury in an experimental rat model. Materials and methods: Twenty-four mature Sprague Dawley female rat was randomly divided into three groups: Sham, I/R, I/R+C. All animals underwent abdominal exploration. To induce I/R injury, an atraumatic vascular bulldog clamp was applied to the right renal pedicle for 60 minutes (ischemia) and later clamp was removed to allow reperfusion in all rats, except for the sham group. In the I/R + C group, 10 mg/kg C was administered intraperitoneally, immediately after reperfusion. After 4 hours of reperfusion, the experiment was terminated with right nephrectomy. Histological studies and biochemical analyses were performed on the right nephrectomy specimens. EGTI (endothelial, glomerular, tubulointerstitial) histopathology scoring and semi-quantitative analysis of renal cortical necrosis were used for histological analyses and superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), total oxidant status (TOS) for biochemical analyses. Results: Histopathological examination of the tissue damage revealed that all kidneys in the sham group were normal. The I/R group had higher histopathological scores than the I/R + C group. In the biochemical analysis of the tissues, SOD, MDA, TOS values were found to be statistically different in the I/R group compared to the I/R + C group (p: 0.004, 0.004, 0.001 respectively). Conclusions: Intraperitoneal cordycepin injection following ischemia preserve renal tissue against oxidative stress in a rat model of renal I/R injury.

Objectives: Ischemia/reperfusion (I/R) injury is a common cause of renal injury and to date, many pharmacological agents have been identified to decrease I/R injury. One of the potential compound that can target I/R injury is chlorogenic acid (CGA). It has potent antiinflammatory, antibacterial, anti-oxidant, analgesic and antipyretic activities in in vitro experiments and in vivo animal models. The aim of the study was to investigate the protective characteristic of CGA on renal I/R injury. Material and Methods: 24 rats were randomly allocated to three groups (n = 8): Sham, I/R+CGA and I/R groups. CGA was administered intraperitoneally at a dose of 20 mg/kg, 10 min before reperfusion. I/R injury was achieved by clamping the left renal artery for 45 minutes, followed by reperfusion for 4 hours. The left kidneys of the rats were examined for tissue damage by histopathological and biochemical examination. For histological evaluation, EGTI scoring system was used. For biochemical examination total oxidant status, total antioxidant status and oxidative stress index were used. The power analysis indicated that 8 subjects per group would be required to produce 80% chance of achieving statistical significance at p < 0.05 level. The results are expressed as mean ± SD. Mann- Whitney U was performed for statistical analysis. Results: Histopathological examination of the tissue damage revealed that all kidneys in the sham group were normal. I-R group had significantly higher histopathological scores than other groups. Histopathological improvement was seen after CGA treatment. TAS, TOS and OSI values of I-R group were significantly higher than sham group (0.88 vs 0.76 (p: 0.004), 13.8 vs 7.04 (p: 0.021) and 0.15 vs 0.09 (p: 0.034), respectively). In CGA treated group TAS, TOS and OSI levels were 0.84, 6.47 and 0.07, respectively. CGA treatment resulted in significant improvement in TOS and OSI parameters. Conclusions: CGA treatment provided marked improvement in renal histology and suppressed oxidative stress. Thus, CGA may have a protective effect in renal tissue against I/R injury.

Paraurethral cysts are rare and occur with obstruction of the Skene duct. In this case, we aimed to present a paraurethral cyst in a baby girl. A 4-day-old newborn was consulted for pediatric urology because of an interlabial mass. In genital examination, a noninvasive mass measuring 2 × 1.5 cm was observed in the interlabial region, and the introitus was completely closed. Ultrasonography showed a cystic lesion localized on the right side of the urethra with a smoothly contoured, thin-walled, hypoechoic structure. The patient underwent puncture under sterile conditions. The content of the mass was mucoid and clear fluid. Paraurethral cysts are often asymptomatic and benign. There is no definitive consensus on treatment.

Background: The aim this study was to explain the underlying etiology of unknown scrotal masses. Case presentation: This study included 3 patients with a intrascrotal mass. One patient was over 50 years. The remaining patients were between the ages of 30-50. Patients had no serious complaints (two complained about having 3 testicles and one complained of swelling in the scrotum for the last 6 months). All patients underwent scrotal exploration under general anesthesia and the specimen was sent for pathological examination. All masses were mobile and encapsulated. The masses were not associated with the testicle. Two cases had classical histologic features of epidermoid cyst and one had scrotal calcinosis in the pathological report. Physical examination, operation, magnetic resonance and histological images of scrotal masses were shown in the figures. Conclusions: This study is important in terms of showing the underlying etiology of the rare scrotal masses.

Clitoromegaly due to non-hormonal causes is rare. In this case, we aimed to present an epidermal cyst that caused clitoromegaly after traditional female circumcision. A 22-year-old African female was referred to our clinic with enlarged clitoris. There is a mobile, soft, nonfluctuant mass with a size of 6 cm originating from the clitoral region at physical examination. Under spinal anesthesia the clitoral mass was excised totally and labioplasty was performed. Histopathologic examination was reported as epidermal cyst. Epidermal cyst should be considered after hormonal reasons are excluded in patients with clitoromegaly who have a history of trauma.

Objective:Nocturnal enuresis (NE) is one of the most common disorders in pediatric urology, and patients often turn to family physicians (FP) and pediatricians (P) initially. The aim of this study was to understand the awareness, self-confidence and suggestions of physicians regarding the management of NE.Materials and Methods:In this study, 360 FP and family medicine residents (FMR), as well as 280 P and pediatrics residents (PR), were contacted through a cellular phone texting system. A simple multiple-choice questionnaire (Surveymonkey®) consisting of 10 questions was used to gather data. The survey included questions about their experience, training, evaluation, and management of NE.Results:A total of 119 FPs and Ps (18.5%) filled the questionnaire. Thirty (25.21%) of the participants were P, 27 (22.69%) PR, 3 (2.52%) FP and 59 (49.58%) FMR. The rate of physicians who encounter at least 5 children with NE per month is 31.33%. The mean self-confidence in the management of NE was 4.5 out of 10. The self-confidence of pediatricians was significantly higher than that of PR and FMR (p

Objective:This study aimed to investigate the protective effects of ellagic acid on testicular ischemia/reperfusion injury in rats.Materials and Methods:Twenty-one Sprague-Dawley rats were randomly divided into three groups: sham, ischemia/reperfusion (I/R), I/R + ellagic acid (EA). All animals underwent left scrotal exploration. In all groups except the sham group, the left testes were rotated 720 degrees clockwise for 3 h and 3 h reperfusion. 10 mg/kg ellagic acid was administered intraperitoneally to the I/R+E group before reperfusion. Then, the left orchiectomy was performed. The testes underwent biochemical and histological examination.Results:There was a significant difference between the sham and the I/R, I/R+EA groups according to the Cosentino system (p

Objective:To evaluate the clinical risk factors contributing to the development of extended spectrum beta-lactamase (ESBL)- producing asymptomatic bacteriuria in myelodysplastic children performing clean intermittent catheterization (CIC).Materials and Methods:The clinical risk factors for ESBL-producing bacteriuria were retrospectively investigated in 60 myelodysplastic children who had asymptomatic bacteriuria and were performing CIC. A total of 60 children were included in this study, 30 children (17 females, 13 males) with ESBL-positive bacteriuria in urine culture were identified as the study group and 30 age- and gender-matched ESBL-negative children (16 females, 14 males) served as controls. All children had neurogenic bladder due to myelodysplasia and had been used anticholinergics. The two groups were compared in terms of age, gender, presence of constipation and motor deficit, antibiotic prophylaxis, number of hospital admission, ultrasound findings, and presence of renal scarring in dimercapto succinic acid scintigraphy and urodynamic findings.Results:The mean age of the children was 77±50 months in study and 78±69 months in control groups. There was no statistically significant difference in terms of maximum bladder capacity, leak point pressure, constipation status and scarring. In study and control groups, 83% and 46% of children were on antimicrobial prophylaxis, respectively (p=0.007).Conclusion:ESBL-producing bacteriuria was found to be associated with long-term antibiotic prophylaxis. Thus, it was concluded that the use of antibiotics for asymptomatic bacteriuria should be kept to a minimum.

Objective:Since microscopic hematuria and pyuria can be observed in patients with a ureteral double-J (DJ) stent in place, urinalysis findings are not considered significant in terms of predicting stent-related infections. This study evaluates the presence of bacterial colonization and the value/ effectiveness of urine tests in predicting the results of DJ stent cultures.Materials and Methods:In the present prospective study, we analyzed data from patients who were treated with a DJ stent placement following endourological surgery due to ureteral stones. DJ stents were removed only after the urine cultures appeared sterile or after a period of empiric antibiotic use. The relationship between urinalysis results and stent cultures was assessed.Results:A total of 65 patients (mean age, 42.6±13.5 years; 16 females and 43 males) were evaluated. Bacterial colonization was detected in 12 (18%) DJ stent cultures with Enterococcus faecalis (n=4), extended-spectrum beta-lactamase producer (ESBL (+) Escherichia coli (n=4), Corynebacterium urealyticum (n=2), candida (n=1) and methicillin-resistant Staphylococcus aureus (n=1) growth being reported. The antibiogram results of the patients that showed colonization in their cultures demonstrated penicillin (n=4), ampicillin (n=4), tetracycline (n=3), imipenem (n=2), and linezolid (n=1) sensitivity. The rate of leukocyte esterase- and nitrite-positive patients, of those having significant number of leukocytes, and urine culturepositive patients in the groups with and without positive urine culture was 58.5%, 32%, 49%, and 7.5% vs 50%, 16.6%, 50%, and 8.5%, respectively. There were no statistically significant differences between the groups (p=>0.05). None of the study patients applied to our hospital with active infection following DJ stent removal.Conclusion:Urinalysis is insufficient in predicting catheter culture results. Based on the results of this study, we assume that stent culture for removed DJ stents is not a necessity; empirical antibiotic therapy with ampicillin-tetracycline should be started in patients with postoperative infection.

Objective:The aim of this study was to evaluate the efficacy and safety of extracorporeal shock wave lithotripsy (SWL) in a large patient group treated with SWL due to kidney stone.Materials and Methods:Data of 1997 patients, who underwent SWL due to renal stone in the at Atatürk University Medical Faculty Clinic of Urology between 2008 and 2013, were evaluated retrospectively. The effect of age, gender, stone location, size and opacity on SWL success, additional procedure requirement and complication rates were evaluated.Results:Six hundred eighty-six patients were female and 1311 were male. The overall rate of success of SWL was found to be 82.6%. The rate of success of SWL was 82.1% in female patients and 82.9% in male patients (p>0.05). Gender, stone location, stone size and opacity were significant predictive factors for the success of SWL (p15 mm was 5.8% (p0.05).Conclusion:Although SWL is less preferred today with the increase of endourological interventions, it remains an effective treatment method in appropriate patients.

Although the standard treatment for testicular tumors is radical orchiectomy in children, testis-sparing surgery (TSS) is an alternative method in selected cases according to tumor size, tumor markers and histopathological findings. In this paper, we present two patients aged 11 and 12 years who underwent TSS in our clinic. Frozen section examination was performed in both patients. Intraoperative ultrasound-guided mass excision was performed in one patient. Histopathological examination revealed an epidermoid cyst in one patient and Leydig cell hyperplasia in the other. TSS may be performed in children with a small testicular mass and negative tumor markers.

Objective: To compare changes in connective, neural and muscle tissues, and extracellular matrix in child and adult patients so that we can create a more objective view on the timing of surgery. Materials and Methods: Twenty-six patients, who were operated for ureteropelvic junction (UPJ) obstruction in our clinic between September 2014 and May 2016, were included in the study. For the evaluation of connective tissue, Masson’s trichrome staining was used. Muscle, extracellular matrix elements and neural tissue were evaluated with immunohistochemistry using alpha-smooth muscle actin (α-SMA), Tenascin C and S100, respectively. Microscopically, the tissues were scored according to their staining density (0: No staining; 1: Minor; 2: Moderate, 3: Dense). Results: There were 12 children and 14 adults in the study groups. The initial evaluation showed no statistically significant difference between studied tissue types with respect to staining density for all parameters (Masson: p=0.414, α-SMA: p=0.204, Tenascin-C: p=0.264, S100: p=0.534). There was no statistically significant correlation between staining density and renal function percentage of the affected kidney (Masson: r=0.454, p=0.051 - α-SMA: r=-0.323, p=0.177 - Tenascin-C: r=0.290, p=0.229 - S100: r=-0.080, p=0.744). Conclusion: Our preliminary study showed some structural changes between adult and child patients but there is no statistically significant difference between the groups with respect to staining density scores. These results state that although UPJ obstruction is an ongoing process, there is no correlation between the histological deterioration degree of the UPJ segment and the loss on renal function for both children and adults.

Objective: The aim of this study was to determine the significance of contralateral testis size in predicting monorchism in pediatric patients with unilateral undescended testis. Materials and Methods: The data of patients who underwent surgical operation by a single pediatric urologist for undescended testis between 2013 and 2016 was evaluated retrospectively. The patients were grouped as having monorchism (M), nonpalpable intra-abdominal testis (NPIAT), and palpable undescended testis (PUDT). The dimensions of the testes were measured ultrasonographically and recorded before operation. Patients with nonpalpable testis underwent diagnostic laparoscopy and patients with PUDT underwent inguinal orchiopexy. Results: A total of 57 children with a mean age of 31 (11-60) months were evaluated. Of the children, 12 had M, 9 had NPIAT and 36 had PUDT with a similar mean age (p>0.05). The size of the descended testis was found to be significantly small in NPIAT* and PUDT** groups compared to the M group (*p0.05). Conclusion: The size of the testis in the scrotum might help to localize the position of the undescended testis.

Objective: The aim of this study was to determine the effectiveness of the voiding dysfunction symptom score (VDSS) in evaluation of children with nocturnal enuresis. Materials and Methods: Four hundred children with nocturnal enuresis were included in the study. They were evaluated with VDSS, physical examination, urinalysis and 2-day voiding diary. All children with nocturnal enuresis symptoms were treated with desmopressin and/or urotherapy. However, children with overactive bladder symptoms were also treated with anticholinergics. Treatment success and change in VDSS were compared and assessed between different treatment methods. Results: Two hundred forty-five children (61.25%) were male and 155 (38.75%) were female. The mean age was 7.6±3.0 years (range: 5-18). The mean VDSS was 9.2±6.3. 35% of children with nocturnal enuresis had concomitant daytime symptoms. 126 children (31.5%) had a VDSS of nine or above and majority of these children were treated with anticholinergic therapy. VDSS questionnaire could not help determine treatment success in children with non-monosymptomatic nocturnal enuresis. However, children treated with urotherapy and desmopressine showed significant difference in VDSSs according to their treatment response. Conclusion: VDSS has shown to decrease after treatment in children with mono-symptomatic nocturnal enuresis. The treatment strategies should be checked and modified if VDSS does not decrease after proper therapy as this would increase the success of treatment.

Objective Nuclear imaging techniques such as 99mTc-dimercaptosuccinic acid (DMSA) and 99mTc-mercaptoacetyltriglycine (MAG-3) are widely used for the diagnosis and follow-up of urinary tract obstructions. Both imaging techniques provide the differential renal function (DRF) in slightly different ways. The aim of this study was to assess the MAG-3 scan as an adjunct or alternative to DMSA for evaluating DRF in children with hydronephrosis. Materials and Methods Eighty-one patients with hydronephrosis were enrolled in this study. Patient age, sex, anteroposterior renal pelvis diameter (RPD) at the time of diagnosis, parenchymal thickness and the DRF percentage found by both DMSA and MAG-3 were recorded. DMSA scintigraphy was used for detecting renal scars and estimating DRF. MAG-3 scintigraphy was used for evaluation of renal clearance, the collecting system’s outflow pattern and estimating DRF. Results A total of 102 renal units (38 left, 22 right and 21 bilateral) were evaluated. High correlation rates were found when we compared both tests’ DRF values according to antero-posterior renal pelvic diameter and patient age (p>0.05). In all groups compared in the present study, both tests demonstrated very similar results and DRF values. Statistical analysis of cut-offs (45%, 40%, 10%) were also similar in both methods (p>0.05, kappa >0.7, r=0.926 Pearson). Conclusion DMSA and MAG-3 are tests that are of assistance in the evaluation of hydronephrosis. Compared to DMSA, MAG-3 also provides valuable information to evaluate DRF values in hydronephrotic renal unit (RU). Avoiding unnecessary DMSA imaging will save time and cost and prevent over-radiation of the pediatric population.

Objective “Traditional subureteral transurethral injection” (STING) and “Double hydrodistention-implantation” (Double-HIT) injection techniques for vesicoureteral reflux (VUR) treatment are a less invasive, yet very effective options. The influence of injection techniques in treatment success is not adequately searched in children with overactive bladder syndrome (OAB). The objective of this study to compare the short-term success rates of STING and Double-HIT techniques in children with OAB-VUR complex. Materials and Methods Children who underwent endoscopic injection for VUR between 2010 and 2013 were retrospectively evaluated. Patients were grouped into two groups according to the surgical techniques (STING or Double-HIT). Success of the treatment was defined with a negative voiding cystourethrogram at the 6th postoperative week. Patients were evaluated according to sex, age, pre- and postoperative reflux grades, laterality, type and volume of bulking agent and presence of OAB. Results Both groups were similar in terms of sex, age, lower urinary tract dysfunction, reflux grade and success rates. Surgical technique, score of pediatric lower urinary tract symptom questionnaire, age, sex, laterality of reflux and type of the bulking agent found to have no effect on the overall success rates (p>0.05). Presence of OAB and/or a high grade reflux were identified as statistically significant predictive factors that could affect the treatment results. Conclusion The short-term surgical success of the double-HIT and STING techniques showed no difference in children with OAB. The presence of a high grade reflux and/or OAB seemed to be the main factors for overall success in endoscopic VUR surgery.

Objective To analyze the parameters that predict the surgical margin positivity after radical prostatectomy for localized prostate cancer. Materials and Methods In this multicenter study, the data of 1607 consecutive patients undergoing radical prostatectomy for localized prostate cancer in 12 different clinics in Turkey between 1993-2011 were assessed. Patients who had neoadjuvant treatment were excluded. We assessed the relationship between potential predictive factors and surgical margin status after radical prostatectomy such as age, cancer characteristics, history of transurethral prostate resection, surgical experience and nerve-sparing technique by using univariate and multivariate Cox regression analyses and t test. Results The overall surgical margin positivity rate was 22.6% (359 patients). In univariate analyses, preoperative prostate specific antigen level, clinical stage, biopsy Gleason score, percentage of tumor involvement per biopsy specimen, transurethral prostate resection history, surgical experience and nerve-sparing technique were significantly associated with positive surgical margin rate. In multivariate analyses, preoperative prostate specific antigen level (OR: 1.03, p=0.06), percentage of tumor involvement per biopsy specimen (OR: 7,14, p

Priapism in a newborn is a rare entity with only 15 cases reported in the literature since 1879. The most commonly detected etiologic factor is polycythemia, but most of the cases are idiopathic. Conservative treatment seems to be sufficient and surgical approach is usually unnecessary. Here, we present a prolonged erection in two newborns which occurred at the first day of life and detumescence was achieved with conservative approach at the 6th and 7th day of life, respectively. We also reviewed the literature to investigate the most adequate evaluation and management criteria
