The biofeedback treatment for non-monosymptomatic enuresis nocturna.

AIMS: Enuresis is a child older than 5 years wetting in discrete portions during sleep. It has two subgroups: monosymptomatic enuresis nocturna (MSEN) and non-monosymptomatic enuresis nocturna (NMSEN). In this research, we specifically aimed to examine the effect of biofeedback in NMSEN. METHODS: We retrospectively analyzed the hospital records of 182 children with NMSEN who were refractory to urotherapy modifications and directed to biofeedback therapies between 2005 and 2010. Enuresis before and after biofeedback therapies was evaluated. One or less enuretic night in a month was defined as success. RESULTS: There were 118 (64%) girls and 64 (35%) boys. With biofeedback therapy, 117 of 182 patients recovered with a success rate of 64% (P < 0.001), but 65 patients still had enuresis. Seventy-two out of 118 girls recovered with a success rate of 61% (P < 0.001), whereas 45 out of 64 boys recovered with a success rate of 70% (P = 0.001). The NMSEN complaints of daytime incontinence, dysuria, urgency, holding maneuvers, and urgency incontinence disappeared significantly concomitant to the enuresis component, as well (P < 0.05). CONCLUSIONS: Biofeedback therapy is an effective treatment option for the enuresis component of NMSEN with a 64% success rate.

The effect of physical activity on varicocele pain and resolution of this pain by different varicocelectomy techniques.

INTRODUCTION: To evaluate the effect of physical activity on varicocele pain and how different varicocelectomy techniques relieve this pain. MATERIALS AND METHODS: Between November 2012 and January 2015, a total of 64 patients with left groin pain and clinical varicocele were enrolled in this study. A visual analogue scale (VAS) classifying the pain in ten scores was used to assess the severity of pain before and after beginning continuous physical activity, and after operations. Patients were randomly divided into three groups. Group 1 had open sub-inguinal varicocelectomy, Group 2 had loupe-assisted sub-inguinal varicocelectomy and Group 3 had microscope-assisted sub-inguinal varicocelectomy. RESULTS: The mean VAS score of patients before and after beginning continuous physical activity was 3.10 +/- 0.9, and 7.65 +/- 0.93, respectively (p = 0.001). These values were 3.36 +/- 0.9, and 7.45 +/- 0.82 in Group 1 (p = 0.001), 2.90 +/- 0.83, and 7.54 +/- 1.29 in Group 2 and 3.06 +/- 1.06, and 7.87 +/- 0.71 in Group 3 (p = 0.001). After the operations, the mean VAS score decreased to 1.90 +/- 1.13 in Group 1 (p = 0.002), 1.63 +/- 1.32 in Group 2 (p = 0.003), and 0.81 +/- 0.71 in Group 3 (p = 0.001). Comparing the postoperative results among the groups, there was no statistical significance between Groups 1 and 2 (p = 0.190), and Groups 2 and 3 (p = 0.378), but a statistically significant difference was determined between Groups 1 and 3 (p = 0.011). CONCLUSIONS: Physical activity has a significant worsening effect on varicocele pain. Microscopic sub-inguinal varicocelectomy offers the best results for pain resolution.

Does structured withdrawal of desmopressin improve relapse rates in patients with monosymptomatic enuresis?

PURPOSE: Relapse after cessation of desmopressin is an important problem in treating patients with enuresis. Structured withdrawal of desmopressin tablets has been shown to decrease relapse rates. However, scientific data are lacking on the structured withdrawal of the fast melting oral formulation of desmopressin. We compared relapse rates of structured withdrawal using placebo and direct cessation in a population of patients with enuresis who were desmopressin responders. MATERIALS AND METHODS: Patients diagnosed with enuresis and responding to desmopressin from 13 different centers were involved in the study. Patients were randomized into 4 groups. Two different structured withdrawal strategies were compared to placebo and direct withdrawal. Sample size was estimated as 240 (60 patients in each group), with a power of 0.80 and an effect size of 30%. Randomization was performed using NCSS statistical software (NCSS, Kaysville, Utah) from a single center. The relapse rates of the groups were compared using chi-square testing. Logistic regression analysis was performed to define the independent factors having an effect on relapse rates. RESULTS: Desmopressin treatment was initiated in 421 patients, and 259 patients were eligible for randomization. Relapse rates were 39 (1%) and 42 (4%) for the structured withdrawal groups, which were significantly less than for direct withdrawal (55, 3%) and placebo (53, 1%). Logistic regression analysis revealed that initial effective dose of 240 µcg, greater number of wet nights before treatment and nonstructured withdrawal were associated with higher relapse rates. CONCLUSIONS: We found that structured withdrawal with the fast melting oral formulation of desmopressin results in decreased relapse rates. Application of a structured withdrawal program was also an independent factor associated with reduced relapse rates, together with lower initial effective dose and number of wet nights per week. Relapse after cessation of desmopressin is an important problem, and in this study structured withdrawal was observed to be associated with decreased relapse rates compared to placebo and direct withdrawal.

A multi-institutional European comparative study of open versus robotic-assisted laparoscopic ureteral reimplantation in children with high grade (IV-V) vesicoureteral reflux.

INTRODUCTION: Traditionally, open ureteral reimplantation (OUR) has been the standard treatment for primary vesicoureteral reflux (VUR) requiring reimplantation. Robotic-assisted laparoscopic ureteral reimplantation (RALUR) is gaining popularity and high success rates have been reported. OBJECTIVE: In this multi-institutional study, we aimed to compare the perioperative and postoperative outcomes of OUR and RALUR for high-grade (IV + V) VUR in children. STUDY DESIGN: A retrospective evaluation was performed collecting data from 135 children (0-18 years) who underwent high grade VUR surgical correction at nine European institutions between 01/01/2009 and 01/12/2020, involving either open or robotic approaches. Institutional review board approval was obtained. Patients with lower grades of VUR (≤III), previous history of open or endoscopic ureteral surgery, neurogenic bladder, or refluxing megaureter in need of ureteral tapering were excluded. Pre-, peri- and post-operative data were statistically compared. RESULTS: Overall, 135 children who underwent either OUR (n = 68), or RALUR (n = 67) were included, and their clinic and demographic features were collected. The mean age of the open group was 11 months (interquartile range [IQR] 9.9-16.6 months), in the RALUR group it was 59 months (IQR 29-78mo) (p < 0.01); the open cohort had a weight of 11 kg (IQR 9.9-16.6 kg) while the RALUR group had 19 kg (IQR 13-25 kg) (p < 0.01). No significant differences were found for intraoperative (1.5 % vs 7.5 %, p = 0.09) or for postoperative complication rates (7.4 % vs 9 %, p = 0.15). Favorable outcomes were reported in the RALUR group: shorter time to stooling (1 vs 2 days), fewer indwelling urethral catheter days (1 vs 5 days), perioperative drain insertion time (1 vs 5 days) and a shorter length of hospital stay (2 vs 5 days) (p < 0.01). The success rate was 94.0 % and 98.5 % in the open and RALUR groups, respectively. The long-term clinical success rates from both groups was comparable:42 vs 23 months for open and RALUR, respectively. DISCUSSION: This study reported a large multicentric experience focusing on high grade VUR. Furthermore, this study compares favorably to OUR in a safety analysis. There was also a trend towards higher success rates with RALUR utilizing an extravesical approach which has not been previously reported. CONCLUSION: RALUR is an efficacious and safe platform to use during ureteral reimplantation for high grade VUR. The overall peri-operative and post-operative complication rates are at least equivalent to OUR, but it is associated with a faster functional recovery and time to discharge. Medium to long term success rates are also equivalent to OUR.

Treatment of Priapism with Automated Red Cell Exchange and Hyperbaric Oxygen in an 11-year-old Patient with Sickle Cell Disease.

Priapism affects up to 50% of all males with sickle cell disease, and there is no standard treatment. Delayed and unsuccessful treatment leads to corporal fibrosis and impotence. It is therefore necessary to determine the best treatment methods for this complication in order to offer effective interventions to all affected patients. Herein we report an 11-year-old patient with sickle cell disease that presented with priapism 72 h after onset, and was successfully treated with automated red cell exchange and hyperbaric oxygen following unsuccessful surgical and conventional interventions.

Bladder regeneration in a canine model using hyaluronic acid-poly(lactic-co-glycolic-acid) nanoparticle modified porcine small intestinal submucosa.

OBJECTIVE: • To determine if hyaluronic acid (HA) can be incorporated into porcine small intestinal submucosa (SIS) through poly (lactide-co-glycolide-acid) (PLGA) nanoparticles to improve the consistency of the naturally derived biomaterial and promote bladder tissue regeneration. METHODS: • Beagle dogs were subjected to 40% partial cystectomy followed by bladder augmentation with commercial SIS or HA-PLGA-modified SIS. • Urodynamic testing was performed before and after augmentation to assess bladder volume. • A scoring system was created to evaluate gross and histological presentations of regenerative bladders. RESULTS: • All dogs showed full-thickness bladder regeneration. • Histological assessment showed improved smooth muscle regeneration in the HA-PLGA-modified SIS group. • For both groups of dogs, urodynamics and graft measurements showed an approximate 40% reduction in bladder capacity and graft size from pre-augmentation to post-regeneration measurements. • Application of the scoring system and statistical analysis failed to show a significant difference between the groups. CONCLUSIONS: • SIS can be modified through the addition of HA-PLGA nanoparticles. The modified grafts showed evidence of improved smooth muscle regeneration on histological assessment, although this difference was not evident on a novel grading scale. • The volume loss and graft shrinkage experienced are consistent with previous models of SIS bladder regeneration at the 10-week time point. • Additional research into the delivery of HA and the long-term benefits of HA on bladder regeneration is needed to determine the full benefit of HA-PLGA-modified SIS. In addition, a more objective biochemical characterization will be needed to evaluate the quality of regeneration.

The effect of intravesical acetylsalicylic acid instillation on tissue prostaglandin levels after partial bladder outlet obstruction in rabbits.

AIMS: To examine whether obstruction changes the expression of prostaglandins (PGs) in bladder, intravesical low-dose aspirin could be used as a new route of drug administration, this way of administration influences PGs' expression, and contractile function of the bladder is protected after treatment. METHODS: Eighteen rabbits were divided into three groups. Sham-operated group (group 1) included 6 rabbits. Twelve rabbits were partially obstructed for 70 days. Six of these 12 rabbits not receiving any treatment constituted obstructed group (group 2). The remaining six rabbits received 2 mg/kg/day aspirin (group 3). One rabbit in each group was evaluated on 1st, 7th, 14th, 28th, 42nd, and 70th days following obstructive surgery. After scarification, the percentage of collagenous area and concentrations of PGE2 and PGF2-alpha were measured. Contractile responses to field stimulation (EFS), carbachol, and potassium chloride (KCl) were determined. RESULTS: Wet tissue PGE2 and PGF2-alpha levels were higher in obstructed group than the other groups. Aspirin decreased the percentage of collagenous area in group 3 compared to the group 2, but this difference was not statistically significant. The strips from aspirin groups resulted in better contractile response to cholinergic stimulation with KCl, but this difference was not statistically significant between the obstructed and aspirin groups. Similarly, carbachol did not elicit significantly greater concentration-dependent contraction in strips from obstructed group compared to those from aspirin groups. Maximum responses to EFS were not significant in aspirin group compared to those from obstructed group. CONCLUSIONS: Intravesical aspirin may have protective effect on partially obstructed bladder.

Robotic simple prostatectomy is a safe and effective technique for benign prostatic hyperplasia: Our single center initial short-term follow-up results for 42 patients.

OBJECTIVE: Benign prostatic hyperplasia is one of the biggest problems of aging men. Prostate surgery is now well defined in the case of failure of medical therapy. Robotic simple prostatectomy is a minimally invasive surgical method with an alternative to open simple prostatectomy in large prostate volumes. We present our simple prostatectomy technique with robot, perioperative, and short-term functional result in our clinic. MATERIAL AND METHODS: Between January 2017 and January 2021, 42 patients underwent simple robotic prostatectomy were retrospectively evaluated. Preoperative, perioperative, and post-operative clinical data were analyzed. Post-operative continence status, voiding, and erectile functions were evaluated using uroflowmetry and international prostate symptom score (IPSS) at sixth week and third month. RESULTS: The mean age of the patients was 71 (66-78) years. No major complications were observed in any of the patients. Urethral catheters were removed on the fourth post-operative day. Except for one case, all of the cases urinated spontaneously after the catheter was removed. One case could not urinate spontaneously, and urethral catheter was placed again. Three days later, the urethral catheter was removed, and patient urinated spontaneously. None of the patients reported stress urinary incontinence or erectile dysfunction. The mean operative time was 112minutes, the mean hospital stay was 1.6 days, the mean post-operative IPSS was 6, and the mean post-operative Q max was 24.4mL s 1. CONCLUSION: Robotic simple prostatectomy may be an effective and safe alternative minimally invasive technique in the treatment of large-volume benign prostatic hyperplasia.

Application of a continent fecal reservoir in patients with cloacal exstrophy.

PURPOSE: Initial enteric diversion in cloacal exstrophy is achieved by ileostomy or end colostomy with formal reconstruction in the form of hindgut pull-through performed in select patients. Those who are not candidates for a pull-through procedure are often left with a permanent incontinent stoma. Additionally due to congenitally deficient intestinal length, some patients with cloacal exstrophy experience short bowel syndrome. We present our surgical technique and clinical experience in 2 patients who were successfully treated with a novel continent cutaneous fecal reservoir. MATERIALS AND METHODS: We devised a fecal reservoir in 2 patients with end ileostomies who were deemed poor candidates for pull-through of the hindgut segment. One of the patients exhibited short bowel syndrome before undergoing reconstruction. A continent cutaneous fecal reservoir was created from all available hindgut and a segment of ileum. A flap valve mechanism was used to create a continent catheterizable channel. RESULTS: Seven years postoperatively both patients are continent of stool and neither has experienced complications attributable to enteric diversion. The patient with short bowel syndrome demonstrated significant improvement in nutritional status as evidenced by rapid weight gain and improvement in serum albumin level. Both patients and their families are highly satisfied with the surgical outcome. CONCLUSIONS: Hindgut and ileum can be combined to create a novel continent fecal reservoir. As an alternative to diverting ileostomy or colostomy, continent diversion offers potential metabolic and social advantages. Select patients with cloacal exstrophy will benefit from this form of enteric reconstruction.

Regional variations in small intestinal submucosa evoke differences in inflammation with subsequent impact on tissue regeneration in the rat bladder augmentation model.

OBJECTIVE: To examine the histological differences in the inflammatory response and regenerative outcomes of distal vs proximal porcine small intestinal submucosa (SIS) grafts in the rat bladder, as SIS from distal small intestine yields reliable and reproducible bladder regeneration, while SIS from proximal portions of small intestine does not provide similar results. MATERIALS AND METHODS: In all, 30 Sprague-Dawley rats underwent hemi-cystectomy followed by anastomosis of a bladder patch of SIS prepared from either distal or proximal small intestine. After bladder harvest, immunohistochemistry was used to quantify mast cells, eosinophils, macrophages, and neutrophils (PMNs). Total cell count per unit area was compared across the time course in univariate and logistic regression modelling. RESULTS: There were more eosinophils and mast cells in proximal SIS grafts, while there were more macrophages and PMNs in distal SIS grafts (all P < 0.05). Trichrome analysis showed increased collagen deposition in proximal SIS grafts and little smooth muscle regeneration. There was also significant graft contracture in proximal SIS grafts compared with distal SIS grafts (P < 0.05). CONCLUSIONS: We conclude that the location of SIS origin may evoke different inflammatory responses, which results in altered bladder tissue regeneration.

Does biofeedback therapy improve quality of life in children with lower urinary tract dysfunction: parents' perspective.

INTRODUCTION: Lower urinary tract dysfunction (LUTD) is a situation that often disrupts the quality of life (QoL) of both the child and the family with daytime and nighttime incontinence. Although the first-line treatment option for children with LUTD is standard urotherapy, biofeedback therapy can be performed in children in which standard urotherapy failed. OBJECTIVE: We studied the biofeedback success in children with LUTD according to parents' expressions. METHODS: We retrospectively analyzed our hospital records of children who were diagnosed with LUTD between 2005 and 2017. In total, 281 patients, refractory to standard urotherapy were included into the study and directed to biofeedback treatment. Their parents completed the dysfunctional voiding symptom scores (DVSS) before and after biofeedback therapy. RESULTS: At the end of the six-month follow-up period, all voiding disorders and voiding patterns were evaluated. According to DVSS, QoL tools before biofeedback treatment 48 (17%) parents appraised that LUTD caused no effect in their children's daily life, 104 (37.8%) expressed little effect, 89 (31%) moderate effect, and 40 (14.2%) serious effect. And, 120 (43%) parents expressed no effect, 95 (34%) little effect, 51 (18%) moderate effect, and 15 (5%) serious effect (P = 0.001) after biofeedback therapy. Biofeedback therapy affected positively the daily life of LUTD's family. The less serious the effect of LUTD on these children's family, the more success rate of biofeedback therapy. The effect of biofeedback therapy was less successful in moderated and serious affected families. CONCLUSIONS: Biofeedback treatment is a non-invasive and effective treatment modality for improving the QoL for LUTD families who were less suffered from LUTD.

Use of second look nephroscopy in children undergoing percutaneous nephrolithotomy.

PURPOSE: We determined the rate of stone clearance in children following percutaneous nephrolithotomy, endoscopic assessment of residual stone and the judicious use of second look nephroscopy. MATERIALS AND METHODS: We retrospectively reviewed the charts of all children undergoing percutaneous nephrolithotomy from 1996 to 2007. Cases were reviewed for pertinent details including preoperative and postoperative imaging, specifics of the procedure and followup. On completion of percutaneous nephrolithotomy the collecting system was assessed via combined nephrostogram and direct nephroscopy. If the collecting system could not be completely visualized or all stone fragments could not be cleared, the patient was referred for second look nephroscopy. Any residual stone present on initial followup imaging constituted a treatment failure. RESULTS: A total of 24 patients underwent percutaneous nephrolithotomy for 30 separate renal calculi. Mean patient age was 9.6 years, and mean stone burden was 2.53 cm. The success rate for percutaneous nephrolithotomy (inclusive of second look nephroscopy) was 87%. Of 30 cases 16 were managed by second look nephroscopy, with findings of residual fragments in all 16. Treatment failure was noted in 1 patient without second look nephroscopy and in 3 patients with second look nephroscopy. Of the 4 patients with treatment failure all were eventually rendered stone-free. CONCLUSIONS: Second look nephroscopy based on endoscopic findings during initial percutaneous nephrolithotomy is a reliable method of detecting and clearing residual stone fragments. Using such a protocol we achieved a high success rate of stone clearance in a population of patients with a significant stone burden.

Is fluoroscopy necessary during flexible ureteroscopy for the treatment of renal stones?

OBJECTIVE: To investigate the feasibility and effectiveness of flexible ureteroscopy (fURS) without fluoroscopy during the treatment of renal stones. PATIENTS AND METHODS: Between April 2013 and August 2018, 744 patients' data were evaluated retrospectively. Of these, 576 patients were included in the study. All fURS were performed by experienced surgeons. All procedures were planned with zero-dose fluoroscopy. But, if fluoroscopy was necessary for any reasons, these patients were excluded from the study. Demographic data, perioperative parameters, stone-free rate (SFR), and complication rates were recorded. RESULTS: Of the patients planned for fluoroless fURS (ffURS), the procedure was successfully achieved in 96.7% (557/576 patients), as 19 patients required fluoroscopy during the procedure for various reasons. In the patients included in the study, the mean (SD) stone size was 11.6 (5.2) mm and the mean (SD) operating time was 39.4 (8.2) min. After the first session of ffURS, the SFR was 83.3% (achieved in 464 patients). Second and third sessions of ffURS were performed in 32 (5.7%) and seven (1.2%) patients, respectively. Overall, the complication rate was 11.8% and all complications were minor (Clavien-Dindo Grade I or II). CONCLUSIONS: The ffURS technique seems to be a safe and effective treatment compared to conventional fURS in patients with renal stones. This procedure should be performed in experienced centers, where fluoroscopy can be considered not to be mandatory during fURS. ABBREVIATIONS CIRF: clinically insignificant residual fragment; CT: computed tomography; EAU: European Association of Urology; (f)fURS: (fluoroless) flexible ureteroscopy; FT: fluoroscopy time; KUB: plain abdominal radiograph of the kidneys, ureters and bladder; mSv: millisievert; PCNL: percutaneous nephrolithotomy; pps: pulse-per-second; rem: roentgen equivalent man; PUJ: pelvi-ureteric junction; SFR: stone-free rate.

Our experience with ureterocystoplasty in bilateral functional kidneys.

OBJECTIVE: We have reviewed the data of the patients in order to evaluate the effectiveness of our ureterocystoplasty technique in augmentation cystoplasty operation. MATERIAL AND METHODS: Data of a total of 16 patients with bilateral functional kidneys who had undergone augmentation ureterocystoplasty between January 1995 and June 2018 which were retrieved during the retrospective archive scanning were included in the study. Ultrasonography (USG), serum blood urea nitrogen and creatinine values and Technetium-99 DTPA (Tc-99 DTPA) scan were used to evaluate the renal function of the patients. Intravenous pyelography (IVP) and USG were used to evaluate the ureters before surgery. Magnetic resonance (MR) urographies were performed in our center. RESULTS: Of the total 16 patients, 10 were male and 6 were female, while ages ranged from 1 to 24 years. Among 16 patients, the most common cause of neurogenic bladder etiology was meningomyelocele. In the urodynamic studies performed before the operation, it was determined that the bladder capacities of the patients were between 40-180 mL and the bladder compliances were 1.0-4.0 cc/cmH2O. At postoperative 3rd months, it was determined that the bladder capacities of the patients were between 180-330 mL and the bladder compliances were between 6.0-24.0 cc/cmH2O. CONCLUSION: Augmentation ureterocystoplasty seems to be an appropriate technique in which successful results are obtained with appropriate patient selection. Besides, complications that may occur due to use of ileal segment are avoided.

Unusual intrascrotal lesions in adults in urological practice. / Lesiones intraescrotales inusuales en adultos en la práctica clínica urológica.

OBJECTIVE: Unusual intrascrotal lesions in adults generally have been described as case reports in the medical literature. We present two lesions observed in two clinics over more than 28 years, with their radiological, pathological and clinical characteristics. METHODS: Retrospective study preformed between 1989 and 2017 in 446 patients undergoing inguinal orchiectomy. Clinical data were obtained reviewing patient` s tables. All patients were evaluated with physical examination, medical history, serum tumor markers (alpha fetoprotein, beta human chorionic gonadotropin, LDH), and scrotal ultrasound in the perioperative period. RESULTS: In 396 cases (88,78%) the diagnosis was germ cell or non-germ cell tumor and the remainder 50 patients (11.2%) presented 15 different intrascrotal lesions. These lesions were rhabdomyosarcoma (1 patient), intrascrotal cavernous hemangioma (1 patient), dermoid cyst (2 cases), epidermoid cyst (4 patients), paratesticular mesothelioma (1 case), parietal testicular tunica vaginalis cyst (2 patients), spermatic granuloma (3 cases). The number of patients with tuberculosis orchitis was 6 and granulomatous orchitis 8. There were 8 patients with fibrous pseudotumor. 1 patient presented testicular plasmocytoma. Metastatic involvement secondary to lymphoma and leukemia appeared in 4 cases. Brucella epididymitis-orchitis 7 cases. 2 cases of adult pure yolk sac testicular tumors. Additional evaluations and treatments were performed depending on histologic diagnosis. CONCLUSIONS: The exact diagnosis of these lesions is difficult due to their rarity and they must always be considered for differential diagnosis.

OBJETIVO: Las lesiones intraescrotales adultas inusuales generalmente se han descrito como un informe de caso en la literatura. Estas lesiones que se observaron en dos clínicas durante más de 28 años se presentan aquí con características radiológicas, patológicas y clínicas.MÉTODOS: Este estudio retrospectivo se realizó entre 1989 y 2017 en 446 pacientes sometidos a orquiectomía inguinal. Los datos clínicos se obtuvieron mediante la revisión de tablas de pacientes. En el período preoperatorio, todos los pacientes evaluados con examen físico, historial de detalles, marcadores tumorales séricos (alfa-fetoproteína, beta-gonadotropina coriónica humana, lactato deshidrogenasa), ultrasonografía doppler escrotal. RESULTADOS: Se diagnosticaron tumores testiculares germinales y no germinales en 396 casos (88,78%) y los 50 pacientes restantes (11,22%) presentaron 15 lesiones intraescrotales diferentes. El tipo de estas diferentes lesiones intraescrotales fueron rabdomiosarcoma paratesticular (1 paciente), hemangioma cavernoso intraescrotal (1 caso), quiste dermoide (2 casos), quiste epidérmico (4 pacientes), mesotelioma paratesticular (1 caso), quiste de capa parietal de túnica testículo vaginal (2 pacientes), granuloma espermático (3 casos). El número de pacientes con orquitis tuberculosa y granulomatosa fue de 6 y 8 pacientes, respectivamente. Los pacientes con pseudotumor fibroso fueron 8 casos. Plasmacitoma del testículo se observó en 1 paciente. La afectación metastásica debida a linfoma y leucemia se observó en un total de 4 casos. Se observó epididimo- orquitis de Burucella en 7 casos. El número de tumores adultos en el testículo puro del saco vitelino fue de 2 casos. Se realizaron evaluaciones y tratamientos adicionales según el diagnóstico histológico. CONCLUSIONES: El diagnóstico exacto de estas lesiones es difícil debido a su rareza y siempre debe considerarse en el diagnóstico diferencial.

Splenogonadal fusion in adults: presentation of three cases and review of the literature.

Splenogonadal fusion (SGF) is a rare congenital anomaly in boys and girls. It commonly presents as a testicular mass treated with an unnecessary orchiectomy. We present 3 cases of SGF diagnosed in adulthood and discuss the published literature focusing on several aspects of this rarity. These cases of SGF of both types presented with the usual complaints. In our first case, orchiectomy was performed since the left testis was hypoplastic and testicular neoplasm could not be ruled out. The testicles could be preserved in the latter 2 cases. The second case is the continuous-type SGF associated with contralateral testicular aplasia and, to our knowledge, this is the first reported case of continuous SGF associated with testicular aplasia. Knowledge of this entity may help prevent unnecessary orchiectomy.

Evaluation of urinary inverted papillomas: a report of 13 cases and literature review.

Inverted papilloma (IP) of the urothelium accounts for 2.2% of urothelial neoplasms. The aim of this study was to report the results of 13 patients with urinary IP, pointing out the clinical features, presentations, treatment options and outcomes. The mean age and mean follow-up periods of the patients were 60.23 +/- 3.25 (range, 44-81) years and 30 (range, 6-42) months, respectively. There was no coexistence of urothelial carcinoma with IP at presentation. Cystoscopy showed a solitary papillary tumor in the bladders of 11 patients and solid pedunculated tumors in the remaining two patients. The site of development was the bladder in 12 cases (92%) and ureter in one (8%) case. Transurethral bladder tumor resection was performed in 12 cases. For the case with IP in the ureter, nephroureterectomy was performed. Pathologic examination demonstrated that seven of the 13 cases were of the trabecular type and six were of the glandular type. Of the 13 cases, two (7%) had recurrence, at 1 year and 1 month and 1 year and 5 months from initial resection. The male to female ratio was 5.5:1. Initial symptoms included macroscopic hematuria in five cases, microscopic hematuria in four, and dysuria and microscopic hematuria in three; one case was asymptomatic. IPs of the urinary bladder are benign tumors that can be treated successfully by transurethral resection and fulguration of the tumor bed. In addition, these lesions must be followed up closely for recurrence and malignant transformation.

Three Distraction Methods for Pain Reduction During Cystoscopy: A Randomized Controlled Trial Evaluating the Effects on Pain, Anxiety, and Satisfaction.

BACKGROUND: Cystoscopy is a safe diagnostic procedure commonly used to evaluate lower urinary tract symptoms. This can cause pain, anxiety, and dissatisfaction in patients undergoing cystoscopy. OBJECTIVES: The aim of this study was to compare the effects on pain, anxiety, and satisfaction of distraction methods used during cystoscopy. DESIGN: Single-center, open-label, randomized, parallel-group trial. SETTING: Cystoscopy unit of a training and research hospital in Turkey. PARTICIPANTS: Male patients ≥18 years of age who underwent rigid cystoscopy for the first time. METHODS: A total of 120 male patients were recruited and randomized into four groups as music, stress ball, video, and control group. Data were collected using visual analog scale for pain and satisfaction, State-Trait Anxiety Inventory for anxiety, and hemodynamic parameters. The primary outcome was the difference with respect to pain scores among intervention groups. Other outcome measures were anxiety and satisfaction scores. RESULTS: Pain severity during cystoscopy was found to be significantly lower in the intervention groups than the control group. In the video group, the severity of pain during cystoscopy was also found to be significantly lower than music and stress ball groups (p = 0.006, p < 0.001). After cystoscopy, anxiety levels were significantly lower and satisfaction levels were significantly higher in the intervention groups than in the control group. Anxiety levels were significantly lower in the video group than music and stress ball groups (p < 0.001, p < 0.001). Satisfaction levels were also significantly higher after cystoscopy in the video group than in the music and stress ball groups (p = 0.018, p = 0.018). CONCLUSIONS: According to this study, distraction methods used during rigid cystoscopy were found to have a reducing effect on pain, anxiety, and dissatisfaction. As the results of the study are evaluated, video should be recommended to be the first preferred distraction method during rigid cystoscopy.

Shock wave lithotripsy or retrograde intrarenal surgery: which one is more effective for 10-20-mm renal stones in children.

OBJECTIVES: To compare shock wave lithotripsy and flexible ureteroscopy in children with renal stone's diameter of 10 to 20 mm. MATERIALS AND METHODS: This is a retrospective study including 79 children, who had renal stone and underwent either shock wave lithotripsy or flexible ureteroscopy between January 2007 and June 2017. Of those, 38 patients underwent shock wave lithotripsy assigned as group 1 and 41 patients underwent flexible ureteroscopy assigned as group 2. Stone-free rate, fluoroscopy time, procedure time, complication rates, hospitalization time, and cost-effectiveness were monitored and included in the analyses. RESULTS: The mean patient age was 4.4 ± 3.5 in group 1 and 4.9 ± 4.1 in group 2. Stone-free rate was not different in both groups in the first and third months of follow-up. The mean fluoroscopy time was statistically significantly longer in group 1 compared to group 2. Procedure and hospitalization times were longer in group 2 compared to group 1. No complications were seen in either groups. The expenditure was calculated as 135.23 and 869.41 Euro per patient for groups 1 and 2, respectively, which shows significant higher cost in group 2. CONCLUSIONS: In this present study, we have shown that shock wave lithotripsy is cheaper, has short hospitalization time and long fluoroscopy time and similar stone-free rate, and has the same efficiency compared to flexible ureteroscopy regarding pediatric renal stones with the diameter between 10 and 20 mm.
