Isolated laparoscopic extra-vesical ureteric reimplantation (I-LEVUR) for upper moiety ectopic ureter without lower moiety vesicoureteric reflux.

To evaluate the feasibility and outcomes of isolated laparoscopic extra-vesical ureteric reimplantation (I-LEVUR) for upper moiety ectopic ureter in patients with non-refluxing lower moiety ureter and avoid reimplanting normal lower moiety orifice. Between 2013 and 2024, 12 patients (8 females, 4 males) with ectopic ureter associated with a duplex system underwent I-LEVUR. Preoperative assessment included ultrasonography, voiding cystourethrography (VCUG), and magnetic resonance urography (MRU)/retrograde pyelogram (RGP). The procedure involved laparoscopic extravesical approach dissecting only the ectopic ureter in lower most part, preserving vascularity, and performing an isolated reimplantation without manipulating lower moiety ureter. Twelve patients, with a median age of 2.8years, underwent I-LEVUR. The mean operative time was 127.5min. No intraoperative complications occurred. Postoperative follow-up (median: 78.5months) showed no cases of ureteral obstruction or significant complications. Urinary continence improved in all patients. Two patients developed mild vesicoureteral reflux, managed conservatively, and one patient had minor urine leak which resolved spontaneously. I-LEVUR is a viable and effective alternative to traditional en bloc reimplantation for upper moiety ectopic ureter. It preserves the normal ureteric orifice, reduces surgical trauma, and offers excellent outcomes in terms of renal function and urinary continence. Further studies with larger cohorts, control group of common sheath reimplantation, randomization, robust statistical validation and longer follow-up are recommended.

Bilateral Ectopic Ureters with Vaginal Insertion in a Duplex Collecting System: A Case Report of a Rare Case

Abstract The usual opening of the ureters is in the trigone of the bladder. However, it may open in an infrasphincteric location causing urinary incontinence with normal voiding. This is more commonly associated with a duplex collecting system in females, albeit, a bilateral occurrence of ectopic ureters with drainage into the vagina is rare. We report a rare case of bilateral occurrence of a duplex collecting system with drainage into the vagina. She was a 3-year-old girl with a complaint of continuous dripping of urine despite normal voiding. There was no history of fever, difficulty with micturition, fecal soiling, back swelling, or pelvic surgery in the past. She had normal female external genitalia with two openings in the vestibule. A computerized tomography urography showed a bilateral duplex collecting system with prompt and symmetric excretion of contrast, and dilated ureters of the upper renal moiety draining into the vagina bilaterally. We reimplanted the ectopic ureters with a resolution of urinary incontinence.

Sonographic Differentiation From Pseudoureterocele of Ectopic Ureter and Ureterocele in Pediatric Patients.

Ectopic ureter and ureterocele need an adequate treatment plan and different surgical interventions. However, some cases appear as intravesical cystic lesions on ultrasound, with ectopic ureter sometimes reported as pseudoureterocele. This study aimed to describe the sonographic imaging findings of intravesical cystic lesions to differentiate between pseudoureterocele and ureterocele. Nineteen patients with duplex collecting system and intravesical cystic lesions that were classified into pseudoureterocele and ureterocele based on the surgical findings were included. The ultrasound findings compared between the 2 groups were as follows: intravesical lesion with/without a covered muscular layer, presence/absence of notch sign within the lesion, and dynamic change in the appearance of intravesical cystic lesions using Fisher's exact test. The lesions in 3 patients were classified as pseudoureterocele due to ectopic ureter and the remaining 16 as ureterocele. Significant differences were observed in intravesical lesions with/without a muscular layer (pseudoureterocele versus ureterocele = 3/0 versus 3/13, P = .021) and the presence or absence of a notch sign within the vesical cystic lesion (pseudoureterocele versus ureterocele = 3/0 versus 3/13, P = .021) between the groups. Although there was a tendency for the dynamic change in the appearance of intravesical cystic lesions to be more detectable in cases with ureterocele than in pseudoureterocele, the difference was not significant (0/3 versus 11/5, P = .058). Sonographic findings, including bladder muscular layer location and the presence of a notch sign within the cystic lesion, were useful in differentiating pseudoureterocele and ureterocele in intravesical cystic lesions in pediatric patients with a duplex collecting system.

Open distal ureteroureterostomy for non-refluxing duplicated collecting system in children: Multicentric study and mid-term outcomes

When indicated, ureteroceles and ectopic ureters in duplicated collecting systems can be managed via upper or lower urinary tract surgical approaches, or a combination of both. Open ureteroureterostomy (UU) has been described to address these conditions in the absence of lower pole (LP) vesicoureteral reflux (VUR). We report outcomes from multiple centers worldwide with mid-term follow-up. Our study consists of a retrospective review of records and imaging of children who underwent open distal UU via inguinal incision for duplicated collecting system without lower pole VUR in institutions from North America, South America, and the Caribbean. Descriptive statistics and univariate analysis were utilized. The records of 127 patients who underwent open distal UU for double collecting system between 2009 and 2022 were reviewed. Of those, 65% were female (n=82), with a mean age at operation of 18 months (range 3-180). Main presentation at surgery included prenatal hydronephrosis (64%, n=81), followed by febrile urinary tract infections (28%, n=36), and urinary incontinence or other (8%, n=10). The patients with antenatal or incidental diagnosis of hydronephrosis were classified as preoperative Society for Fetal Urology (SFU) grade 3 (n=64) and 4 (n=54) (96%). Those who were classified with SFU grade 0-2 (4%) had symptomatic clinical presentations including febrile urinary tract infections (UTIs) (n=3), urinary incontinence (n=3), and a 12-year-old patient with recurrent abdominal pain (n=1). Mean operative time from skin incision to skin closure was 86min (range 45-240). Mean hospital stay was estimated at 1.1 days (range 0.5-4). In our cohort of 127 patients, 3 (2%) developed Clavien-Dindo grade I (2 with ureteral stent displacement and 1 with a urine leak/managed conservatively), 6 (5%) with grade II (3 febrile and 3 non-febrile UTIs managed with oral antibiotics), and 2 (2%) with grade IIIb complications (urine leaks requiring surgical management), which were appropriately treated. None presented grade IV or V complications. A double J stent was used in 56 patients (44%), and a Penrose drain was left in 10 (8%). A total of 125 children (98%, n=125/127) showed sonographic improvement of hydronephrosis, or resolution of symptoms with stable ultrasound findings. Successful outcome was similar for both ureterocele and ectopic ureter subgroups: 49/49 patients with ureterocele showed 100% improvement, 76/78 children with ectopic ureter showed improvement in 97% of the cases. On univariate analysis, outcomes were similar regardless of the use of ureteral stents (p=0.11). Mean follow-up was 28.2 months (range 12-85). Open distal UU is a good alternative for the definitive surgical management of ectopic ureters and ureteroceles without LP VUR. This multicentric and mid-term follow-up study demonstrates that open distal UU offers high success rates, low morbidity, short operative times and hospital stays, and satisfactory aesthetic outcomes. Additionally, the surgery is performed extra-peritoneally and may not require the use of stents or drains, depending on surgeon preference. Further investigations are being conducted to determine the role of UU in the settings of double collecting systems associated with ipsilateral LP VUR.

A misleading case of Müllerian anomaly: fibroid degeneration and growth involving nonfunctional, noncommunicating rudimentary horn

ObjectiveTo report a rare, misleading fibroid degeneration involving a non-functional, non-communicating horn in a woman with a unicornuate uterus. While the presence of a functional rudimentary horn may lead to signs and symptoms that recommend its removal, non-functional cases are rarely reported, and due to their apparent functional inactivity, the need for their removal has never been reported. No previous report showed the possibility of a degenerative process in a non-functional rudimentary horn causing patient discomfort. DesignThis is a step-by-step narrated video showing a unique case of fibroid degeneration and growth of a non-functional, non-communicating rudimentary horn in a unicornuate uterus (ASRM classification 2021) and its surgical management. SettingUniversity Academic Hospital ‘‘A.O.U. delle Marche – Università Politecnica delle Marche” Ancona, Italy. SubjectA 48-year-old Caucasian nulliparous premenopausal woman was referred to our institution because of abdominal pain and an enlarging adnexal mass. Her personal history showed primary infertility with a previous diagnosis of unicornuate uterus. Given the possibility of ectopic ureters in these occurrences, a complete computed tomography scan was performed, and no genitourinary alterations were found. Pre-operative imaging (ultrasound evaluation, computed tomography, and magnetic resonance) provided a provisional diagnosis of a suspicious ovarian fibroma. InterventionsConsidering the patient’s age, lack of desire for pregnancy, and volumetric increase of the adnexal mass, a laparoscopic intervention to perform mass removal and prophylactic bilateral salpingectomy was planned. The patient was counseled about the low risk of an underlying malignant transformation. Therefore, the decision to remove the intact mass via a mini-laparotomy at the end of the surgery was shared.Once the abdominal cavity was entered, the right unicornuate uterus was found in anatomical continuity with the ipsilateral broad ligament, fallopian tube, and ovary. These structures were wholly attached to the right pelvic wall.On the other side, cranially compared to the right hemi-uterus, a roundish myoma-like mass was detected in direct connection with the left broad ligament, fallopian tube, and ovary.In light of a changed intraoperative finding, the amputation of the left rudimentary horn and prophylactic bilateral salpingectomy were performed. Main outcome measuresShowing the fibroid degeneration and growth of a non-functional, non-communicating rudimentary horn in a unicornuate uterus (ASRM classification 2021) treated laparoscopically. ResultsLaparoscopic removal of the uterine horn was successful, and no intra- and postoperative complications occurred. The patient was in good health at the six-month follow-up visit. The histopathological examination confirmed the fibroid degeneration and the absence of endometrium. ConclusionThe lack of symptomatic cases of rudimentary non-functional horns reported in the literature led gynecologists to consider them a silent Mullerian anomaly. This unique case demonstrates that even non-functional rudimentary horns can undergo symptomatic transformation processes requiring surgery. This information may be helpful for more comprehensive counseling of women and for considering the possibility of this occurrence in the diagnostic work-up of misleading Müllerian anomalies. With this in mind, surgical treatment can also be better planned as the technical aspects change compared to what is expected for an adnexal pathology.

Vesicovaginal Fistula Secondary to Left Ectopic Ureter in a 3-Year-Old Female with Left Ureter-Duplication in Tamale Teaching Hospital, Ghana: A Case Report

Purpose: Vesicovaginal fistula (VVF) is a pathological connection between the bladder and vagina, primarily caused by gynaecological surgery, obstructed labour, and cesarean section. VVF significantly impairs quality of life and is prevalent in developing countries, with Africa seeing up to 130,000 new cases annually. Surgical repair, especially transvaginal approaches, remains the primary treatment. Paediatric cases of VVF, often linked to congenital anomalies like ectopic ureter, are rare and complex to manage. Methodology: We report a case of a 3-year-old female with continuous urinary leakage since birth, initially flagged for renal anomalies via prenatal imaging. Clinical examination was normal with no distress or developmental issues. Diagnostic assessments, including abdominal ultrasound and micturating cystourethrogram (MCUG), revealed left hydronephrosis, hydroureter, and a definitive vesicovaginal fistula. A CT Urogram confirmed the diagnosis, showing contrast leakage into the vagina. Findings: Diagnostic cystoscopy revealed a normally positioned right ureteric orifice, while the left was aberrantly positioned near the bladder neck. Culposcopy identified a ureterocele in the posterior fornix of the vagina. During laparotomy, a dilated left distal ureter was observed entering the vagina, indicating true ureter duplication. The surgical intervention involved left ureteric reimplantation using the antireflux method, successfully resolving the anomaly. Post-operative recovery was smooth, with significant improvement in urinary symptoms and no recurrence or complications noted during follow-up. Unique contribution to theory, policy and practice: VVF secondary to ectopic ureter in paediatric patients is rare but manageable with early diagnosis and tailored surgical intervention. Our case underscores the importance of a multidisciplinary approach and the efficacy of ureteral reimplantation in treating complex congenital anomalies, leading to favourable outcomes and symptom resolution.

Presentation, diagnosis, and outcomes of cats undergoing surgical treatment of ectopic ureters.

To describe the signalment, treatment, complications, and outcomes of cats treated surgically for ectopic ureters. Retrospective, multi-institutional study. Twelve client-owned cats. Medical records of cats diagnosed with unilateral or bilateral ectopic ureters were reviewed and analyzed. Data reported included signalment, clinical signs, diagnostics, open celiotomy, or cystoscopic surgical interventions, and outcomes. Seven of the 12 cats in the study population were female or female spayed and the median age at time of presentation was 4 years, with an interquartile range (IQR) of 6 months-14 years. Presurgical diagnostic imaging diagnosed ectopic ureters by abdominal ultrasound (8/10), contrast enhanced computed tomography (3/3), fluoroscopic urography (3/4), or cystoscopy (6/7). Eight of 12 cats had extramural ectopic ureters and six cats were affected bilaterally. Eight affected cats underwent ureteroneocystostomy, one cat underwent neoureterostomy, two cats underwent cystoscopic laser ablation, and one cat underwent nephroureterostomy. Immediate postoperative complications occurred in three cats; one cat required additional surgical intervention. Short-term complications occurred in three cats, and long-term complications in two cats. All cats that underwent surgical or cystoscopic intervention had improvement of their urinary incontinence scores, with complete resolution in 11 cats. Surgical correction of ectopic ureters in cats is associated with good long-term outcomes. Ectopic ureters in cats are commonly extramural and bilateral. Postoperative outcomes were acceptable and there were few postoperative complications, with varying forms of surgical correction. Ectopic ureters in cats are rare but urinary incontinence can be corrected or improved successfully with surgery.

Clinical analysis of 80 patients with oblique vaginal septum syndrome

Objective: To investigate the clinical features, diagnosis and treatment of oblique vaginal septum syndrome (OVSS). Methods: The clinical data of 80 patients with OVSS admitted to The Second Hospital of Hebei Medical University from July 2005 to July 2023 were retrospectively analyzed. According to the classification system of OVSS proposed by Female Genital Anomalies Study Group, Chinese Obstetricians and Gynecologists Association in 2021, the patients were divided into four groups. The clinical manifestations, accompanied urinary system abnormalities, diagnosis and treatment methods and treatment outcomes were observed. Results: According to the above classification system, among the 80 patients with OVSS, 35 patients (44%, 35/80) were categorized as type Ⅰ, 33 patients (41%, 33/80) were categorized as type Ⅱ, 2 patients (3%, 2/80) were categorized as type Ⅲ and 10 patients (13%, 10/80) were categorized as type Ⅳ. The main onset symptom of patients was periodic abdominal pain (70%, 56/80), vaginal bleeding (20%, 16/80), dysuria or fecal impaction (15%, 12/80), vaginal mucopurulent discharge (10%, 8/80). The morbidity of combined urinary system abnormalities was 88% (70/80), and the most common urinary system abnormality was ipsilateral renal agenesis (81%, 65/80). Bilateral kidneys were normal in 13% (10/80) patients, and 6% (5/80) were combined with other urinary system abnormalities. A total of 74 patients underwent vaginal oblique septectomy or septum excision. Five of the 10 patients with type Ⅳ underwent hysterectomy on the cervical atresia side, 4 patients received hysteroscopy combined with cervicoplasty+oblique septotomy or septum excision, and one patient selected delayed menstruation. Two patients underwent laparoscopic resection of the dysplasia kidney and ectopic ureter which opening to the vagina. Eleven patients with endometriosis cyst, hydrosalpinx or empyema underwent laparoscopic surgery. Conclusions: The main symptom of type Ⅰ and Ⅳ patients is abdominal pain, while the main symptom of type Ⅱ and Ⅲ patients is bleeding. Magnetic resonance imaging (MRI) has advantages in the evaluation of complex OVSS, and MRI is recommended before operation to exclude other axial reproductive tract dysplasia and complex urinary system dysplasia. If there is leakage of urine, vaginal discharge or complex deformity, it is necessary to multidisciplinary discussion and formulate a reasonable surgical plan. The first treatment is related to the prognosis of patients especially children, and should be highly valued.

Applicability and Suitability of the Embryological-Clinical Classification of Female Genital Malformations: A Systematic Review.

Complex urogenital malformations are clinically highly relevant; thus, they must be appropriately diagnosed and classified before initiating treatment. Background/Objectives: This study aimed to evaluate the applicability and suitability of the embryological-clinical classification of female genital malformations. Methods: A systematic review of cases of genital malformations reported in the literature from 2000 to 2020 was conducted. Case reports and series with the following combinations: "female genital tract" AND (malformation OR anomaly OR müllerian anomaly OR uterine anomaly OR cervical anomaly OR vaginal anomaly OR cloacal anomaly OR urogenital sinus); and "female genital tract" AND (renal agenesis OR ectopic ureter) were searched. A total of 3124 articles were identified, of which 824 cases of genital malformation were extracted. The characteristics of each malformation were included in a database for further analyses. Results: Using the embryological-clinical classification, 89.9% of the published cases and 86.5% of the 52 cases defined as unclassifiable by their authors have been classified in this review. In 73 cases (72.2%), the classification of the malformation using the AFS system was incomplete because although the type of uterine anomaly of the AFS classification matched that of the embryological-clinical classification, characteristics of the urinary system or the vagina were overlooked when using the AFS system. Following a dispersion matrix, we have been able to show that the embryological-clinical classification system is able to classify and subclassify the genitourinary malformations more accurately. Conclusions: The applicability of the embryological-clinical classification has been confirmed after classifying most of the cases of genital malformation previously published. This system also provides a more complete and accurate classification than other classifying systems exclusively based on Müllerian duct development or uterovaginal parameters, demonstrating its suitability.

Ectopic Ureter Opening in Vagina: A Rare Cause of Nonfunctional Kidney and Urinary Incontinence in a Pediatric Patient

Ectopic Ureter Opening in Vagina: A Rare Cause of Nonfunctional Kidney and Urinary Incontinence in a Pediatric Patient

Ectopic Ureter: Spectrum of Magnetic Resonance Imaging Findings.

This study aims to describe the MRI findings of six patients with ectopic ureters in a tertiary care institute. A retrospective analysis was conducted on six patients presenting to the Department of Radiodiagnosis at Sawai Man Singh (SMS) Hospital, Jaipur, India, with ectopic ureters. Data were collected from the 3 Tesla (3T) Philips MRI scanner (Koninklijke Philips N.V., Amsterdam, Netherlands) from 2021 to 2023. The mean age was 21.6 years, with an equal male-to-female ratio (1:1). Most patients presented with urinary incontinence (50%, n = 3), followed by abdominal pain. Only 16.6% (n = 1) were associated with a duplex collecting system. In males, the most common site was the seminal vesicle, observed in 66.6% (n = 2), followed by the urethra in 33.4% (n = 1) of cases. One patient with an ectopic opening into the seminal vesicle had Zinner syndrome. In females, the ectopic site was found to be the vagina in all three patients. Ectopic ureter is a rare anomaly of the urinary system, often associated with other urinary system anomalies and a few syndromes. Clinical presentations range from the patient being asymptomatic to renal failure; therefore, a high index of suspicion and appropriate imaging are necessary for early diagnosis and timely treatment.

Ureteral duplication with ectopic implantation of the ureter into the prostatic urethra

An ectopic ureter is a ureter that terminates in or below the bladder neck. The incidence of ectopic ureter remains unclear because this malformation is often asymptomatic. Eighty percent of ectopic ureters are associated with a duplicate ureter. In our case, it was a 29 years old man, who consulted for intermittent pelvic pain. The patient underwent a prostatic magnetic resonance imaging (MRI), which showed an ectopic ureteral abruption at the level of the prostate. The uroscanner showed a ureteral duplicity with a silent superior kidney.

Ipsilateral ureteroureterostomy. A safe alternative in complete duplicated collecting system with associated pathology

To report our experience in patients with complete double renal system with only one system affected, with the surgical technique of uretero-ureteral anastomosis. Retrospective study of patients with double renal system with involvement of one of the systems, treated with uretero-ureteral anastomosis technique between January 2015 and May 2022. The variables of age, specific pathology of the affected system, preoperative study, days of hospitalization, postoperative complications (leakage, obstruction, infection), and follow-up time were evaluated. We analyzed 26 procedures in 25 patients, mean age 36.8 months (range: 8-80); 53.8% had ectopic ureter, 23% ureterocele, 11.5% sphincteric ureterocele, and 11.5% VUR of the lower system. All were studied preoperatively with urethrocystography and 65% with scintigraphy. 50% of the operated systems showed signs of renal atrophy. The average hospital stay was 2.2 days (range: 1-7). In an average follow-up of 26.5 months (range: 3-77), one patient presented leakage, no patient presented signs suggestive of obstruction, and one patient presented febrile urinary tract infection with persistent lower-grade reflux. In our experience, the uretero-ureteral anastomosis technique proved to be an easy and safe alternative to reproduce, with a success rate of 96%, 11% of grade I complications, and 4% of grade II complications according to the Clavien-Dindo classification.

Receiver operating characteristics of computed tomography (CT) compared to cystoscopy in diagnosis of canine ectopic ureters: Thirty-five cases.

The aim of the study was to determine receiver operating characteristics (ROC) of computed tomographic excretory urography (CTEU) in predicting cystoscopic findings of ureteral anatomy. Retrospective cohort study. Thirty-five client-owned dogs. The medical records of dogs referred for suspected ectopic ureters were reviewed. Inclusion criteria included CTEU findings reported by board-certified radiologists, followed by rigid cystoscopy with or without ureteral cystoscopic laser ablation (CLA). Data included signalment, urinary incontinence degree, body condition score, weight, degree of colon distension, CTEU and cystoscopy findings. ROC analysis was used to compare CT-predicted ureteral orthotopia/ectopia to cystoscopy findings. Additionally, ROC of CT predicted ureteral orifice locations was analyzed. Regression covariate analysis was performed to identify factors that may have influenced accuracy of diagnosis. The ability of CT to identify a normal and intra-or extramural ectopic ureters conclusively and correctly was 13/26 (50%) and 32/41(78%), respectively. Sensitivity and specificity of identifying extramural versus intramural ureters was 2/7 versus 30/46 (29 vs. 65%) and 61/63 versus 17/24 (97 vs. 71%), respectively. Ectopic orifice determination sensitivity and specificity varied widely depending on location from 0% to 76% and 67% to 97%, respectively. Covariate analysis failed to identify interfering factors. CT did not accurately predict anatomy of ureters; CT findings may need confirmation by cystoscopy and possibly intraoperative fluoroscopy prior to determining if CLA is indicated or not. Our results may be of importance for surgeons interpreting the CTEU findings. CTEU prediction of the location of the ureteral orifice shows low sensitivity especially in or close to the urethral sphincter area.

Surgical Challenges of Bilateral Duplex Kidney with Ectopic Ureters

Abstract The bilateral duplex system is extremely uncommon, and only a few cases have been documented in the literature. It may manifest as a bifid renal pelvis and partial or complete ureteric duplication, with or without ectopic insertion of the ureter. An ectopic ureter is more problematic when there is significant vesicoureteral reflux, incontinence, and/or blockage. The optimal course of treatment is considered to be ureteral reimplantation rather than heminephrectomy. We describe the management strategy for a case of bilateral duplex kidneys with bilateral ectopic ureters in a growing female child.

Ureteric Clipping for the Treatment of Urinary Incontinence in Girls With Ectopic Ureters: Predicting Who Is Going to Dilate and Does It Matter?

ObjectivesTo assess the effectiveness and midterm follow up of laparoscopic upper pole ectopic ureteral clipping to treat urinary incontinence in girls with duplex kidneys and non/poorly functioning upper pole moieties. To see if pre-operative characteristics increased the likelihood of significant post-operative dilatation and whether this dilation has clinical significance. MethodsA database review identified children who had undergone ureteric clipping at our institution. Patient details assessed included: age at presentation, age at procedure, significant past medical history, pre-operative investigations, operative time, length of stay, post-operative symptoms, post-operative renal tract ultrasound findings and the need for subsequent intervention. ResultsSix girls underwent clipping between March 2018 - May 2021. The mean age at presentation and surgery were 77months (39-186) and 86months (44-193) respectively. The mean operative time was 94 minutes (range 66-128 minutes). The median length of stay was 1 day (range 0-3 days). All the girls were dry immediately after the procedure. During a mean follow up of 51 months (29-66) all children have remained symptom free and required no further intervention. Two children have developed significant (>30mm) but stable ureteric dilatation after clipping but have remained asymptomatic and therefore are continuing on conservative follow up. Both these children had dilated ureters (>10mm) pre operatively. Conclusion:Ureteric clipping is quick, safe and effective option in dealing with incontinence due to ectopic upper pole ureters in girls. Children with pre-operative ureteric dilation seem to be at increased risk of post-operative dilation. However, as they remain asymptomatic, the clinical significance of this dilatation is unclear.

Our experience with management of congenital urological pathologies in adulthood: What pediatric urologists should know and adult urologists adopt in pediatric practice experience.

To summarize our experience in the management of congenital anomalies in the kidney and urinary tract (CAKUT) in adults. We conducted a retrospective chart review of all adult patients who underwent primary surgical intervention for CAKUT between 1998 and 2021. The study included 102 patients with a median age of 25 (interquartile range, 23-36.5). Of these, 85 (83.3%) patients reported normal prenatal ultrasound, and the remaining 17 (16.7%) patients were diagnosed with antenatal hydronephrosis. These patients were followed-up conservatively postnatally and were discharged from follow-up because of the absence of indications for surgical intervention or because they decided to leave medical care. All studied adult patients presented with the following pathologies: 67 ureteropelvic junction obstructions, 14 ectopic ureters, 9 ureteroceles, and 6 primary obstructive megaureters, and the remaining 6 patients were diagnosed with vesicoureteral reflux. Forty-three percent of the patients had poorly functioning moieties associated with ectopic ureters or ureteroceles. Notably, 67% of patients underwent pyeloplasty, 9% underwent endoscopic puncture of ureterocele, 3% underwent ureteral reimplantation, 6% underwent endoscopic correction of reflux, 7% underwent partial nephrectomy of non-functioning moiety, and the remaining 9% underwent robotic-assisted laparoscopic ureteroureterostomy. The median follow-up period after surgery was 33 months (interquartile range, 12-54). Post-operative complications occurred in 5 patients (Clavien-Dindo 1-2). Patients with CAKUT present clinical symptoms later in life. Parents of patients diagnosed during fetal screening and treated conservatively should be aware of this possibility, and children should be appropriately counseled when they enter adolescence. Similar surgical skills and operative techniques used in the pediatric population may be applied to adults.

Persistent urinary incontinence in female Golden Retrievers following laser ablation of intramural ectopic ureters may be associated with the presence of historical urinary tract infection.

To identify predictive factors for postoperative continence in female Golden Retrievers following cystoscopic-guided laser ablation of intramural ectopic ureters (CLA-EU). 41 client-owned female entire Golden Retrievers with uni- or bilateral intramural ectopic ureter(s) were retrospectively enrolled. Patients were diagnosed with ectopic ureters with a combination of ultrasonography and cystoscopy. CLA-EU was performed for all dogs so that each ureteral opening was considered to be in an appropriate position by a single operator. All dogs had short-term follow-up 4 weeks and long-term follow up > 10 weeks after the procedure via telephone, which included urinary continence scoring. Clinical factors and ultrasonographic and cystoscopic findings from initial presentation were evaluated to identify predictive factors for postoperative continence. Short-term urinary continence was achieved in 46.3% of dogs with no additional medical therapies. Presence of historical urinary tract infections prior to CLA-EU (OR, 0.130; 95% CI, 0.020 to 0.621; P = .018) was negatively correlated and ureteral dilatation (OR, 34.260; 95% CI, 1.813 to 2,143; P = .043) was positively correlated with likelihood of urinary continence. Long-term urinary continence was achieved in 63.4% of dogs, and presence of historical urinary tract infections was negatively prognostic (OR, 0.173; 95% CI, 0.023 to 0.856; P = .048). Female Golden Retrievers undergoing CLA-EU have similar outcomes to those reported for other mixed-breed cohorts with > 30% of dogs failing to regain urinary continence. Historical urinary tract infections were significantly associated with both short- and long-term urinary continence in our population.
