Introduction: Delayed intraperitoneal bladder rupture is a rare clinical occurrence, frequently overlooked and misdiagnosed due to its nonspecific clinical manifestations. However, literature provides only a limited number of cases reporting delayed intraperitoneal bladder rupture resulting from blunt abdominal injury., Patient Concerns: A 72-year-old female pedestrian was struck by a vehicle and experienced sudden, severe abdominal pain on the 8th day following the injury. Abdominal B-ultrasound revealed a significant accumulation of peritoneal effusion. The abdominal puncture retrieved serosanguinous ascites. Then the patient was promptly transferred to our hospital. Upon transfer, the physical examination revealed the patient vital signs to be stable, accompanied by mild abdominal distension, slight tenderness, tension, and an absence of rebound tenderness. Urinalysis detected microscopic hematuria, while contrast-enhanced computed tomography (CT) revealed considerable fluid accumulation in the abdominal cavity, without evidence of solid organ damage, and the bladder was adequately filled., Diagnosis: The diagnosis of delayed intraperitoneal bladder rupture primarily relied on intraoperative observations., Interventions: An emergency exploratory laparotomy was performed, revealing a linear rupture at the dome of the bladder. Subsequently, the bladder rupture was repaired., Outcomes: Postoperative cystography demonstrated full recovery and the patient was discharged 28 days post-surgery. The postoperative recovery was uneventful without any complications., Conclusions: A well-distended bladder observed in CT does not definitively rule out the potential for bladder injury. False negatives may occur due to incomplete bladder filling during CT cystography. Retrograde cystography can identify cases missed by CT cystography. In cases of substantial intra-abdominal free fluid, surgical intervention should be actively considered for patients with blunt abdominal trauma without concurrent solid organ damage., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Background: To investigate urodynamic abnormalities associated with vesicoureteral reflux (VUR) in toilet-trained children., Methods: The data of 157 children who were diagnosed with vesicoureteral reflux and referred to our hospital between 2013 and 2022 were retrospectively examined. The urodynamic parameters were analyzed and correlated with age, gender, lower urinary tract symptoms (LUTS), reflux severity, and laterality., Results: Overall, 131 (83.4%) patients had abnormal urodynamic findings with a male-to-female ratio of 1:1.4. The most common pathological finding was detrusor overactivity (DO), identified in 101 (64.3%) patients, followed by dysfunctional voiding (DV) in 74 (50.3%) patients. Children with VUR grades II and III exhibited a greater percentage of abnormal urodynamic findings than children with grades IV and V. The prevalence of DO was higher in children younger than 10 years old with unilateral and lower-grade VURs. DV was more frequent in children older than 10 years, with bilateral VUR, and higher grade VUR. The prevalence of LUTS, bowel and bladder dysfunction (BBD), and urinary tract infection (UTI) was higher among children with abnormal urodynamic findings., Conclusions: Children with VUR have a high incidence of urodynamic disorders. Urodynamic dysfunction may contribute to the pathogenesis of VUR, especially in mild cases., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Melanosis of the urinary bladder, so-called melanosis vesicae, is a rare condition characterized by dark, velvety bladder mucosa observed by cystoscopy examination. Up to 20 examples have been reported in the English literature, and the etiology of this disease still needs to be discovered. We present an 82-year-old woman with a history of pelvic organ prolapse-associated urinary symptoms. The patient was found to have pigmented urinary bladder mucosa on cystoscopy and underwent a total hysterectomy and bladder mucosal biopsy. Histologically, pigmented granules were evident in the bladder stroma and epithelium, highlighted by Periodic Acid-Schiff (PAS) stain, suggestive of lipofuscin in nature. We outline the diagnostic features of bladder melanosis, discuss the diagnostic mimickers, and thoroughly review the literature on the subject., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose: Bladder and bowel dysfunction is a common but underdiagnosed pediatric entity which may represent up to 47% of pediatric urology consults. The objectives of this observational study were to determine functional 1-year outcomes following standard treatment of bladder and bowel dysfunction in both control and neuropsychiatric developmental disorder groups using validated questionnaires, and to perform an initial cost analysis., Materials and Methods: This was a prospective observational study conducted across a number of academic European centers (July 2020-November 2022) for new bladder and bowel dysfunction patients. Parents completed a sociodemographic survey, information pertaining to prior neuropsychiatric developmental disorder diagnoses, as well as a number of validated functional scores., Results: A total of 240 patients were recruited. In the control bladder and bowel dysfunction group, the baseline Dysfunctional Voiding Scoring System and Childhood Bladder and Bowel Dysfunction Questionnaire scores were 20% and 17.% lower, respectively, after 1 year compared to the neuropsychiatric developmental disorder group. The change in improvement was diminished for the neuropsychiatric developmental disorder cohort in both Dysfunctional Voiding Scoring System and Childhood Bladder and Bowel Dysfunction Questionnaire scores. The odds ratio of full symptom resolution was 5.7 in the control cohort compared to the neuropsychiatric developmental disorder cohort. A cost analysis on prescribed medications at referral led to a total cost of €32,603.76 (US $35,381.00) in the control group and €37,625.36 (US $40,830.00) in the neuropsychiatric developmental disorder group., Conclusions: This study demonstrates that pediatric patients with a neuropsychiatric developmental disorder exhibit more severe bladder and bowel dysfunction at baseline and throughout treatment with a lower overall quality of life, as well as 15.4% higher medication costs at referral. It is also important that parents' and caregivers' expectations are managed regarding higher levels of treatment resistance for functional bladder and bowel issues.

Importance: Vesicouterine fistula (VUF) is an iatrogenic consequence of cesarean section in the vast majority of cases. The worldwide increase of cesarean delivery rates is likely to be accompanied by a rise of this complication, and surgery is the mainstay treatment., Objective: The aim of the study is to assess current evidence on VUF pathogenesis and management., Study Design: The study is a case report and literature review on PubMed and Embase spanning over the past 2 decades., Results: An early VUF developed after a cesarean section at full cervical dilation and concurrent incidental bladder injury. A transabdominal extravesical repair was performed 3 months after cesarean delivery. Both the cystotomy and hysterotomy were repaired in a double-layer fashion with no interposition flap. A contemporary literature review including 25 patients showed that VUF was repaired transabdominally in 21 patients (84%), and an open approach was adopted in 18 patients (85.7%). In most patients, the uterine side was closed with a single-layer suture and an interposition flap was used to reinforce the repair. Concomitant hysterectomy was performed in 6 patients (24%). Overall, successful term pregnancies were reported in 2 patients after VUF repair., Conclusions: Vesicouterine fistula is a rare event and is commonly associated with cesarean sections, especially those with a concurrent bladder injury. Careful and meticulous surgical technique may prevent the occurrence of this condition. Delayed repair and double-layer closure of both bladder and uterus, with or without an interposition flap, are recommended., Competing Interests: The authors have declared they have no conflicts of interest., (Copyright © 2023 American Urogynecologic Society.

Case: We present a case of spontaneous extra-peritoneal rupture of an acquired diverticulum an elderly male with symptoms of bladder outlet obstruction who presented in emergency with acute abdomen., Outcome: The acute phase was managed conservatively with bladder drainage and intravenous antibiotics. He recently underwent Transurethral Resection of Prostate. He is asymptomatic on follow-up., Conclusions: Acquired bladder diverticulum are rare in adults and are mostly seen in patients with high pressure bladder due to bladder outlet obstruction. Atraumatic extraperitoneal ruptures of diverticulum are uncommonly reported., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Congenital lower urinary tract obstruction (LUTO) is a rare but significant condition affecting fetal urinary tract development. LUTO has a range of etiologies, with posterior urethral valves (PUV) being the most common cause. The prenatal diagnosis of LUTO plays a crucial role in recognizing the condition and guiding management decisions. Prenatal ultrasound serves as the primary tool for identifying LUTO, with key findings including megacystis, bladder wall thickening, oligohydramnios, hydronephrosis, and the 'keyhole sign' indicating dilatation of the posterior urethra. We present a case of congenital LUTO with a rare complication of spontaneous fetal bladder rupture and urinary ascites, treated by peritoneo-amniotic shunt placement., Case Presentation: A 27-year-old pregnant Caucasian women was referred at 28 weeks of pregnancy due to the presence of megacystis and bilateral hydronephrosis on routine ultrasound and suspicion of LUTO. Repeat ultrasound at 29 weeks showed significant fetal ascites, oligohydramnios and resolution of megacystis and hydronephrosis, after which diagnosis of spontaneous bladder rupture was made. Despite ascites aspiration and amnio-infusion, there was persistent ascites and oligohydramnios. A peritoneo-amniotic shunt was placed with resolution of ascites and normalization of the amniotic fluid volume. At 35 weeks, relapse of the megacystis was observed with bilateral pyelectasis and oligohydramnios, possibly due to healing of the bladder rupture, after which elective cesarean section was planned. Cystography confirmed spontaneous healing of the bladder rupture and the presence of posterior urethral valves, which were resected in the neonatal period with cold knife incision. Total follow-up of 8 years continued to show positive ultrasonographic results and good renal function, but the child suffers from bladder dysfunction, manifesting as overactive bladder disease., Conclusions: LUTO might lead to important renal dysfunction and pulmonary hypoplasia in case of increasing disease severity. Spontaneous bladder rupture might improve renal prognosis, acting as a pop-off mechanism by decompression of the urinary tract. However, fetal bladder rupture is rare and only few cases have been reported. Prenatal intervention can be considered for moderate or severe LUTO, but the benefit for long-term outcome remains uncertain and further studies are needed., (© 2023.

Purpose: To establish a parameter-based grading system for evaluating bladder trabeculation (BT)., Materials and Methods: A retrospective analysis was conducted on children diagnosed with posterior urethral valve (PUV) or neurogenic bladder (NB) who underwent voiding cystourethrogram (VCUG), urodynamic testing, and urological ultrasonography between January 2016 and October 2022. Cases involving urologic surgery, secondary bladder pathology, and an interval of more than 12 months between examinations were excluded. A parameter named Bladder Dispersion (BD) was calculated through fluoroscopic images, and the grading system was developed as follows: BD < 40 (Grade 0), 40 ≤ BD < 60 (Grade 1), 60 ≤ BD < 90 (Grade 2), BD ≥ 90 (Grade 3). Grades 0-1 were classified as low-risk group, while grades 2-3 were classified as high-risk group. Analysis of variance, Kruskal-Wallis test, and Chi-square test were performed to compare urodynamic results and complications across different grades and groups., Results: A total of 74 patients were eligible to participate, which included 46 boys (62.2%) and 28 girls (37.8%), the mean age was 75.18 ± 48.39 months. Among them, 11 (14.9%) were PUV, 50 (67.6%) were NB, and 13 (17.5%) were PUV and NB. Significant differences were observed in maximum detrusor pressure, post-void residual urine ratio, and compliance among grades 0-3. Severe hydronephrosis and histories of urinary tract infection were more prevalent in the high-risk group., Conclusion: A reliable grading system with objective standards was proposed which could aid in the assessment of BT severity., (© 2023.

Background: Blunt trauma to the urinary bladder is common with penetrating injury being a rare occasion. Most common entry pint for penetrating injuries includes buttock, abdomen and perineum with thigh being rare. There are a number of complications that may develop as a result of penetrating injury with vesicocutanous fistula being a rare occurrence that usually presents with typical sign and symptoms., Case Presentation: We present a rare case of penetrating bladder injury through medial upper thigh as an entry point that had complicated into vesicocutaneous fistula with atypical presentation of long-standing pus discharge that had been managed by incision and drainage several times with no success. MRI demonstrated a presence of fistula tract and a foreign body (piece of wood) in-situ confirmed the diagnosis., Conclusion: Fistulas are a rare complication of bladder injuries and can cause negative impact on the quality of life of patients. Delayed urinary tract fistulations and secondary thigh abscesses are uncommon therefore a high index of suspicion is needed for early diagnosis. This case emphasizes the importance of radiological tests in aiding the diagnosis and ultimately proper management., (© 2023. The Author(s).)

Inguinal hernia is one of the most frequent pathologies in surgery and is defined by the passage of abdominal or pelvic contents through the inguinal orifice [1]. However, an inguinal hernia is said to be of the bladder when the contents involve the bladder [2]. It is rare and most often discovered intraoperatively [3]. We report a case of left inguinal bladder hernia diagnosed by ultrasound. This was a 74-year-old patient who consulted for dysuria associated with bilateral inguino-scrotal swelling. A vesico-prostatic ultrasound was performed using a Samsung ultrasound scanner equipped with high and low frequency probes and a pulsed and color Doppler mode. At the end of this examination, the diagnosis of a left inguinal hernia of the bladder was made., (Le comité de rédaction se réserve le droit de renvoyer aux auteurs avant toute soumission à l'avis des lecteurs les manuscrits qui ne seraient pas conformes à ces modalités de présentation.

Spontaneous bladder rupture is a relatively rare medical emergency that can be easily misdiagnosed. Although spontaneous bladder rupture is more common in those with previously diagnosed bladder conditions, this phenomenon may also occur in patients with an otherwise insignificant past medical history. Early diagnosis and treatment are critical to avoid fatal complications. Here, we present a 49-year-old male with insignificant past medical history who was diagnosed with spontaneous bladder rupture after the attempted placement of a Foley catheter.

Rationale: Amyloidosis is a group of benign lesions characterized by extracellular deposition of amyloid proteins. Amyloidosis lesions can occur in various organs of the body, but rarely in the urinary system. Amyloidosis in the bladder trigone is extremely rare., Patient Concerns: An 80-year-old female patient presented with painless whole-course gross hematuria with reddish urine and no blood clots, accompanied by right lumbar discomfort., Diagnosis: Based on the patient's medical history and cystoscopy findings, the relevant literature was reviewed and a preoperative diagnosis of bladder tumor was made, although bladder amyloidosis was not excluded. Postoperative pathology ultimately revealed bladder amyloidosis., Interventions: The patient underwent resection of bladder tumor and ureteral stent implantation. Postoperatively, the patient was maintained on antibiotics and oral colchicine treatment., Outcomes: Two months after surgery the patient reported that the gross hematuria had disappeared, and that the right lumbar discomfort was significantly relieved.Cystoscopy showed no obvious recurrence in the operative area, but magnetic resonance imaging (MRI) suggested recurrence. The patient refused partial cystectomy, and the ureteral stent was removed., Lesson: The clinical manifestations of bladder amyloidosis are nonspecific, and under cystoscopy can be easily confused with bladder tumors. Accurate diagnosis of bladder amyloidosis relies on histopathology. Transurethral resection of bladder tumors or partial cystectomy is an option for surgical treatment; the latter should be performed if the ureteral opening is involved., Competing Interests: The authors have no conflicts of interests to disclose., (Copyright © 2022 the Author(s).

Study Objective: To describe the diagnostic workup and laparoscopic management of a noncommunicating left uterine rudimentary horn (class U4aC0V0 European Society of Human Reproduction and Embryology/European Society of Gastrointestinal Endoscopy Classification) with communicating endometriotic bladder nodule., Design: Step-by-step description of the surgical treatment., Patient: A 33-year-old woman with unicornuate uterus and a left-side noncommunicating rudimentary horn affected by primary infertility, mild dysmenorrhea (visual analog scale score 6), severe catamenial dysuria (visual analog scale score 10), and catamenial hematuria., Setting: Noncommunicating rudimentary horns are rare Müllerian anomalies present in 20% to 25% of women with a unicornuate uterus. It is associated with severe dysmenorrhea, pelvic pain, subfertility, and poor obstetric outcomes and usually presents with cyclic pelvic pain that starts early after the menarche. Endometriotic bladder nodules are present in 1% to 2% of patients with endometriosis. In the literature, there are no reported cases of noncommunicating rudimentary horn with communicating endometriotic bladder nodules. Surgical excision of the rudimentary horn is the treatment of choice. In our case, the 2-dimensional/3-dimensional ultrasound revealed a right unicornuate uterus with a left noncommunicating rudimentary horn with hematometra. The uterine fundus presented «gamma sign» vascularization. In addition, a bladder endometriotic nodule (16 × 15 mm) communicating with hematometra was displayed. Magnetic resonance imaging demonstrated no additional malformations. Diagnostic hysteroscopy revealed a single cervix without vaginal malformation and small right uterine cavity with single tubal ostium. At laparoscopy, using hysteroscopic transillumination, a clear plane of dissection was identified between the rudimentary horn and the uterus confirming the presence of a noncommunicating horn. Evaluation of the abdominal cavity showed bilateral normal adnexa with normal ovaries. Chromopertubation showed a patent right Fallopian tube and obstructed left tube., Interventions: A left salpingectomy using bipolar and the ultrasonic energy was performed. The utero-ovarian ligament was transected, and the left ovary was preserved. The left ovary was suspended at the pelvic wall, the retroperitoneum was opened, the ureter was identified, and the left uterine artery was temporary occluded. The left round ligament was transected and the left paravesical space was developed. With a lateromedial approach, we opened the vesicouterine septum to dissect the bladder from the rudimentary horn. The endometriotic bladder nodule was gently detached from the uterine horn with a lateromedial approach. The left uterine artery was coagulated and dissected at level of the cervix. A solution of vasopressin was injected between the uterine horn and the uterus. Resection of the rudimentary horn was performed. The peritoneum was closed. The temporary occlusion of the uterine artery was removed. The specimen was placed in a bag and removed using an extracorporeal tissue extraction technique., Conclusion: The late clinical presentation of our patient with only mild dysmenorrhea could be explained by the drainage of the hematometra from the noncommunicating horn into the endometriotic bladder nodule. The bladder symptoms in patients with Müllerian anomalies should be carefully investigated. The laparoscopic removal of rudimentary horn with mobilization of communicating bladder nodule when present is a safe and feasible method to improve symptomatology., (Copyright © 2022 AAGL.

Objective: To compare clinical findings and urodynamic parameters according to trabeculation grade and analyze their correlations with trabeculation severity in neurogenic bladder caused by suprasacral spinal cord injury (SCI)., Methods: A retrospective chart review was performed of neurogenic bladder caused by SCI. Bladder trabeculation grade was compared with SCI-related clinical parameters and bladder-related urodynamic parameters., Results: In SCI patients, factors such as disease duration, bladder capacity, detrusor pressure, peak detrusor pressure values, and compliance were significantly different between different grades of bladder trabeculation, while neurological level of injury, completeness, and detrusor sphincter dyssynergia had no clear relationship with bladder trabeculation grade. In the correlation analysis, vesicoureteral reflux was moderately correlated with trabeculation grade (correlation coefficient 0.433), while the correlation coefficients of disease duration, involuntary detrusor contraction, and bladder filling volume were between 0.3 and 0.4., Conclusion: Bladder trabeculation with suprasacral-type neurogenic bladder was graded. Although disease duration was positively correlated with bladder trabeculation grade, differences in the neurological level of injury or American Spinal Injury Association Impairment Scale score were not observed. Bladder volume, peak detrusor pressure, compliance, reflex volume, and vesicoureteral reflux also showed significant differences according to trabeculation grade. Vesicoureteral reflux was moderately correlated with trabeculation grade.

Urinary incontinence results from disorders of the lower urinary tract or neurologic diseases either of the nerve supply to the bladder/urethra or within the central nervous system. Congenital causes include patent urachus and ectopic ureter. Coordination of lower urinary tract function involves the interaction of both the sympathetic and parasympathetic system as well as somatic branches of the central nervous system. Well-recognized causes of incontinence include equine herpes virus 1 myeloencephalopathy, polyneuritis equi (neuritis of the cauda equina), and sacral/coccygeal trauma. Idiopathic bladder paralysis is characterized by bladder paralysis and sabulous cystitis in the absence of overt neurologic deficits., Competing Interests: Disclosure No commercial or financial conflicts of interest.

Background: While bladder dysfunction is observed in the majority of patients with human T cell lymphotropic virus type 1 (HTLV-1)-associated myelopathy (HAM), it is also observed in patients who do not fulfill all diagnostic criteria for HAM. These patients are classified as having possible or probable HAM/TSP. However, it remains unclear whether the severity and progression of bladder dysfunction occurs similarly between these two groups., Objective: Compare the severity and evolution of bladder dysfunction in HTLV-1-infected patients with possible and definite HAM/TSP., Methods: The present prospective cohort study followed 90 HTLV-1 patients with possible HAM/TSP and 84 with definite HAM/TSP between April 2011 and February 2019. Bladder dysfunction was evaluated by bladder diary, overactive bladder symptoms scores (OABSS) and urodynamic studies. Bladder dysfunction progression was defined as the need for clean self-intermittent catheterization (CIC)., Results: At baseline, nocturia, urgency and OABSS scores were worse in definite compared to possible HAM/TSP patients. The main urodynamic finding was detrusor overactivity, present in 77.8% of the patients with definite HAM/TSP versus 58.7% of those with possible HAM/TSP (P = 0.05). Upon study conclusion, the cumulative frequency of patients requiring CIC increased in both groups, from 2 to 6 in possible HAM/TSP and from 28 to 44 in definite HAM/TSP patients. The estimated time to need for CIC was 6.7 years (95%CI 6.5-7.0) in the possible HAM/TSP group compared to 5.5 years (95%CI 4.8-6.1) in the definite HAM/TSP group., Conclusions: Although both groups showed similarities in bladder dysfunction and tended to progress to requiring CIC over time, patients with possible HAM/TSP presented less severe manifestations at baseline and progressed more slowly than those with definite HAM/TSP., Competing Interests: The authors have declared that no competing interests exist.

Background: Ichthyosis is a rare skin disorder, in which the shedding of squamous cells is altered. Intravesical ichthyosis is an extremely rare condition. There is evidence for an association with intravesical condylomata accuminata, caused by urogenital infections of the human papilloma virus. These lesions are generally benign but known to be of a carcinogenic potential and therefore should be treated immediately and followed-up closely., Case Presentation: We present the case of a 39-year-old woman who presented with recurrent urinary tract infections. During cystoscopy diffuse black pigmented flat bladder tumours were visualized. After transurethral resection the pathological report diagnosed an ichthyosis vesicae., Conclusion: We recommend a complete resection with frequent clinical and cystoscopic follow-up. Furthermore, testing for the human papilloma virus should be performed and a vaccination should be offered to the patient. As ichthyosis vesicae is a rare phenomenon, there is an evident lack of clinical data regarding therapy, prognosis and follow-up. With our report, we want to emphasize the need for further research., (© 2021. The Author(s).)

Reservoir induced bladder rupture is a rare complication of inflatable penile prosthesis (IPP) revision surgery. Our aim is to review the literature and describe our experience with this complication using two case reports that involved reusing an in-situ reservoir. In each case, an episode of gross hematuria indicated that a bladder rupture had occurred. From our experience, we propose ways to possibly avoid and if necessary, manage this rare complication.

Purpose: The primary purpose of this study was to evaluate the effect of the fatty acid amide hydrolase (FAAH) inhibitor ASP3652 on efficacy and safety in patients with Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS). The secondary purpose was to evaluate phenotyping based on Hunner's lesions (HL)., Methods: In this randomized trial, adult female patients with moderate/severe IC/BPS received 12 weeks of treatment with an oral dose of ASP3652 (50, 150, or 300 mg twice daily) or placebo. A Bayesian model was employed using accumulating data to adjust the randomization probability and to analyze the primary efficacy variable (change from baseline to end of treatment in Mean Daily Pain [MDP; range 0-10]). Study outcomes and patient characteristics of patients with and without HL (HL+ and HL-) were compared., Results: In total, 287 patients were randomized. The 300 mg dose group (n = 97) showed the largest effect, i.e., a mean change from baseline to end of treatment of -1.73 in MDP. However, the mean difference from placebo was 0.02. The probability that this dose was better than placebo was 13.5%. Adverse event incidence was low and similar between study groups. HL+ patients were older and had more severe symptoms than HL-. An association was suggested in HL+ patients between changes in micturition frequency and MDP (R = 0.41 [95% CI 0.18, 0.63]), which was not observed in HL- (R = 0.04 [95% CI -0.16, 0.29])., Conclusion: ASP3652 was safe and well tolerated, but did not show efficacy in IC/BPS. The observed differences between HL+ and HL- suggest that IC/BPS diagnosis and treatment may be approached differently in these two phenotypes., Trial Registration: EudraCT number 2011-004555-39, date of registration: 2012-05-07.

Background: An association between bladder-bowel dysfunction (BBD) and urinary tract infection (UTI) is well-known. However, a question less explored is whether children with UTI early in life also have increased prevalence of BBD after they are toilet-trained. In this study, consecutively selected children with pyelonephritis during their first year of life were assessed for BBD at pre-school age., Methods: Ninety-two children (51 boys) hospitalized due to pyelonephritis during their first year of life were assessed for BBD at median age 5.4 years. A validated BBD questionnaire, along with urine flow and residual volume measurements, was used for diagnosing BBD. During follow-up, the group was well-characterized regarding renal status, vesicoureteral reflux (VUR), and recurrent UTI., Results: BBD was diagnosed in 35/92 (38%), of which the majority was sub-diagnosed with dysfunctional voiding (DV). There was a strong association between BBD and recurrent UTI during follow-up (p < 0.0001), but only a slight association with VUR status at presentation. Nevertheless, in the group with both BBD and VUR, recurrent UTI was four times higher (12/13, 92%) than in children who had neither VUR nor BBD (23%), (p = 0.0008). BBD was also associated with kidney damage (p = 0.017)., Conclusion: In children with pyelonephritis during the first year of life, 38% had BBD at pre-school age, regardless of whether they had VUR or not. The study shows an important association between BBD and recurrent UTI, so an assessment of BBD is therefore recommended for pre-school children with UTI, especially when they have history of pyelonephritis during infancy.

A 5 yr old male neutered domestic shorthair with intermittent signs of urinary tract obstruction was suspected of having a blood clot in the urinary bladder secondary to trauma. The cat was hospitalized and received standard supportive therapy for urinary tract obstruction with urinary catheterization, with the addition of intravesical saline flushes in an attempt to promote bladder clot lysis. The cat was subsequently discharged after voluntary urination was observed. The cat was represented 28 hr after discharge because of clinical signs consistent with urinary tract obstruction. The cat was hospitalized and intravesical tissue plasminogen activator (tPA) infusions (0.5 mg of tPA in 10 mL of saline with 2 hr dwell time q 8 hr) were administered to break down the bladder clot (2.78 × 4.46 cm). Thirty-two hours after starting tPA, the clot was no longer visible on ultrasound. The cat was discharged with no recurrent symptoms in the subsequent 11 mo. This is the first report of tPA being used for dissolution of bladder clot in a cat. There were no observed complications, suggesting that intravesical instillation of tPA may be a safe and efficacious therapy in cats, similar to the previously reported successes in dogs and humans., (© 2021 by American Animal Hospital Association.)

Objective: To describe the management and the fertility-enhancing potential of surgery in an infertile patient with deep-infiltrating endometriosis and adenomyosis externa., Design: Video case report., Setting: Minimally invasive and robotic gynecologic surgery unit of a university hospital., Patient(s): A 31-year-old nulliparous patient with dysmenorrhea, dysuria, dyspareunia, and primary infertility., Intervention(s): Bimanual examination, transvaginal ultrasound, and magnetic resonance imaging (MRI) were performed as a comprehensive preoperative workup. The findings were consistent with bladder endometriosis and a 4-cm right pararectal cystic mass suggestive of adenomyosis externa. Laparoscopic excision of all visible endometriosis was performed. A pararectal lesion was found, completely developing in the retroperitoneal spaces, from the right medial pararectal space to the rectovaginal space, reaching the pelvic floor fascia without infiltration of the levator ani muscle. According to Koninckx classification, this kind of lesion corresponds to type III endometriosis or adenomyosis externa. Nerve-sparing eradication of the nodule was performed. The decision to use these techniques was taken with the intention to treat the patient, and not with the aim of testing the procedures performed. Therefore, as a common clinical practice in our institution and for the above reasons, there was no need for consultation of the institutional review board for approval., Main Outcome Measure(s): Improvement of symptoms and spontaneous conception after surgical removal of all endometriotic implants., Result(s): There were no intraoperative or postoperative complications, and the patient was discharged after 3 days. She discontinued postoperative hormone therapy with gonadotropin-releasing hormone analogue after 3 months because she desired fertility. She conceived spontaneously after 2 months of attempting. She delivered vaginally and had no complications during pregnancy and labor. Neither recurrence of pain symptoms nor voiding or rectal dysfunctions were reported by the patient., Conclusion(s): In the management of a case of deep endometriosis, the preoperative assessment should be carefully carried out to give the surgeon the most accurate information about the extent of the disease and the patient's main objectives. Imaging techniques such as ultrasound and MRI play a fundamental role along with the clinical evaluation in also detecting lesions that are not visible at first laparoscopic inspection. In this case of a young woman without any detectable fertility issues except for endometriosis, the laparoscopic excision of endometriosis was feasible, safe, and effective in improving the patient's fertility and pain symptoms. The fertility-enhancing potential of complete eradication of pelvic endometriosis, including removal of deep posterior localizations such those presented in this case, has been hypothesized by various investigators. It has been suggested that skilled surgical management for symptomatic deep endometriosis may be followed by a high pregnancy rate, with most pregnancies resulting from postoperative natural conception even in patients with primary infertility., (Copyright © 2020 American Society for Reproductive Medicine.

Background: Fetal bladder rupture causing urinary ascites is uncommon. It is generally related to invasive fetal medicine procedures or obstructive disorders such as in posterior urethral valves in male fetuses. An exceptional case of spontaneous bladder rupture in a female fetus occurred in a pregnant woman treated with high doses of opiates in an intensive care unit. This unusual obstetric situation leads to discussion of the possible causes of fetal bladder rupture, its management, and the pediatric prognosis., Case Presentation: We report the case of a 30-year-old nulliparous black woman with a history of mesenteric cystic lymphangioma and multiple bowel resections leading to chronic malabsorption. During her pregnancy, our patient presented with an occlusive syndrome and major bilateral renal dilation. Urinary derivation resulted in iatrogenic bilateral ureteral perforation. Our patient thus presented with major uroperitoneum, bilateral pleural effusion and acute renal failure, treated by thoracic drainage and bilateral nephrostomy. Postoperative pain required treatment with level III analgesics. In this context, 5 days after morphine treatment introduction an enlarged fetal bladder was observed, followed 3 days later by voluminous fetal ascites. The diagnosis of spontaneous bladder rupture was suspected. After multidisciplinary discussion, expectant management was decided. At 31 weeks and 4 days gestation, our patient went into spontaneous labor with a subsequent vaginal delivery. The infant required resuscitation and paracentesis of ascites at birth. Her neonatal course was favorable with a simple urethral bladder drainage. Cystography at day 9 was normal. At 2 years of follow-up, the mother and the child have a normal course., Conclusions: An iatrogenic origin of megacystis in a female fetus must be evoked in the event of maternal administration of high doses of opiates in the second part of her pregnancy. In our case, the megacystis was followed by spontaneous bladder rupture at 30 weeks of gestation, with a favorable maternal fetal issue.

Introduction: Bladder Bowel Dysfunction (BBD) has been described in patients with Down's Syndrome (DS). Our aim was to report the incidence, demographics, presentation, complications and management of the bladder in DS patients with BBD., Methods: A systematic review was performed using PRISMA guidelines and search terms "{[(trisomy 21) OR down's syndrome]} AND [("non-neurogenic") OR voiding dysfunction]" in the search engines MEDLINE and SCOPUS. We also include a case series from two paediatric urology centres., Results: A total of 38 patients with BBD and DS were included. Mean age was 12 years (newborn to 21 years), the male:female ratio was 2:1. Functional constipation (90%), recurrent urinary tract infections (38%) and enuresis were common at presentation (56%), while over 56% patients required surgical intervention. Medical treatment and behavioral modification were less successful while intermittent catheterisation did not work., Conclusion: This study reviews the largest cohort of patients with BBD in DS. It is common with serious consequences requiring operative intervention. Usual interventions are unreliable due to poor compliance. Early identification and management protect the renal tract. Regular screening for urogenital anomalies in DS is currently not performed. We recommend a thorough history of bladder function in DS patients to identify these cases early.

Introduction: Interstitial cystitis/bladder pain syndrome (IC/BPS) and endometriosis are coexistent diagnoses in 48%-65% of women with chronic pelvic pain (CPP), suggesting that dual screening may be warranted. To further investigate the clinical relationship and risk factors between these two conditions, we performed a retrospective review of our large IC/BPS patient data registry., Materials and Methods: We evaluated IC/BPS patients who were prospectively enrolled into our registry who completed validated questionnaires and underwent therapeutic hydrodistension, during which anesthetic bladder capacity (BC) and Hunner's lesion (HL) status were recorded. Demographic/medical history were reviewed. IC/BPS patients with co-occurring endometriosis diagnosis versus those without were compared using descriptive statistics as well as multivariate regression analyses to determine predictors of co-occurring disease., Results: Of 431 IC/BPS participants, 82 (19%) were also diagnosed with endometriosis. These women were significantly younger, had increased prevalence of non-low BC (> 400 cc), and decreased prevalence of HL (p < 0.05). Patients with co-occurring endometriosis also had increased prevalence of irritable bowel syndrome (IBS), CPP, fibromyalgia, and vulvodynia (p < 0.05). On multivariate analysis, non-low BC (OR 4.53, CI 1.004-20.42, p = 0.049), CPP (OR 1.84, CI 1.04-3.24, p = 0.04), and fibromyalgia (OR 1.80, CI 1.03-3.14, p < 0.04) were significantly associated with a diagnosis of endometriosis., Conclusions: Patients with IC/BPS and co-occurring endometriosis were significantly more likely to carry a non-bladder centric IC/BPS phenotype as well as several comorbid, systemic pain diagnoses. This study characterizes features of a target IC/BPS phenotype that could potentially benefit from endometriosis and systemic pain syndrome screening.

As far as we know this is the first report on bulking agent injection into intravesical ectopic ejaculatory orifices reported in the English literature. During a follow-up period of 23 months, the child was free of episodes of epididymo-orchitis. Deflux injection in this rare anomaly of intravesical refluxing ducts had prevented irreversible damage to the testes from recurrent EO. Thus, it may be a better option than vasectomy when antibiotic treatment fails., (Copyright © 2020 Elsevier Inc. All rights reserved.)

We review the role of the heart, kidneys, and bladder in the pathophysiology of nocturia and nocturnal polyuria. Lower urinary tract symptoms such as nocturia have often been associated with lower urinary tract dysfunction. It is known that the bladder contributes to nocturia in the case of low functional capacity, urgency, and detrusor overactivity. Heart diseases, especially arterial hypertension and congestive heart failure, are closely related to nocturnal polyuria. The main mechanisms include renal hyperfiltration and elevated atrial natriuretic peptide. A number of drugs frequently used in cardiovascular disorders are implicated in nocturia; diuretics, calcium channel blockers, and β-blockers induce nocturnal polyuria and thus nocturia, whereas alpha-blockers improve nocturia. Among the different forms of hypertension, nondipping arterial hypertension has been associated with a higher risk of nocturnal polyuria. Besides the role of the kidneys in nocturia linked to arterial hypertension, chronic kidney disease is an independent predictor of nocturia through an osmotic diuresis mechanism. Some evidence suggests a close relationship between the heart (nondipping arterial hypertension), kidneys (chronic kidney disease), and nocturia/nocturnal polyuria. These complex interactions between the heart, kidneys, and bladder warrant a multidisciplinary approach in patients with nocturia. PATIENT SUMMARY: We review the different mechanisms that lead to nocturia and nocturnal polyuria. The complex interactions between the heart, the kidneys, and the bladder warrant a multidisciplinary approach in patients with nocturia. Careful investigation of the cause of nocturia can improve its management., (Copyright © 2019 European Association of Urology. Published by Elsevier B.V. All rights reserved.)

Objective: Urinary retention caused by bladder clots can be frustrating because such blood clots are difficult to remove. We established a novel technique in which hydrogen peroxide is applied to evacuate bladder clots., Methods: In this single-center retrospective study, we evaluated 31 patients with retention of blood clots in the bladder who underwent emergency evacuation using hydrogen peroxide., Results: The patients comprised 17 men and 14 women with mean age of 61.2 years (range, 42-82 years). Hydrogen peroxide solution and a 20-Fr three-cavity Foley catheter with large-diameter side holes were used for manual bladder irrigation in all patients. The bladder blood clots were successfully removed in 27 patients. The remaining four patients could not tolerate the symptoms of urinary retention and had to resort to surgery., Conclusion: Hydrogen peroxide solution for manual bladder irrigation can improve the efficiency of bladder blood clot evacuation. This is a simple and effective option for managing bladder clot retention.

Purpose: Bladder hernias are asymptomatic in most cases and are found incidentally during exploration for inguinal hernia repair. The treatment of inguinal bladder hernia is either reduction or resection of the herniated bladder, followed by herniorrhaphy. We present a case series with preoperative diagnoses, along with their surgical outcomes., Methods: We retrospectively reviewed the medical records from a single institution over a 5-year period (2012-2017) of five patients with diagnosis of large bladder inguinal hernia. Demographics, clinical status, medical history, anatomical structure of the hernia, and surgical outcomes were all analyzed., Results: Patients' median age was 51 years (range 45-81 years). The median size of the hernial sac was 13 cm (range 8-20 cm). The diagnosis was made with computed tomography in three patients and with ultrasonography and cystography in two patients. Median length of hospital stay was 2 days (range 1-6 days), and median length of follow-up was 28 months (range 18-72 months). All patients continue to be alive and well, without hernia recurrence. The five cases are described separately along with their surgical managements., Conclusion: The main objectives in treatment of inguinal bladder hernia are to preserve the voiding function and to avoid bladder injuries in a tension-free hernia repair. To our knowledge, this is the first series of cases in which all inguinal bladder hernias were diagnosed preoperatively.

BACKGROUND Endometriosis is a chronic and benign condition in which endometrial glands and stroma are present outside the uterine cavity. The pathogenesis of endometriosis is not fully understood; however, several mechanisms have been hypothesized. Endometriosis is a common clinical presentation in gynecology, but affecting the urinary tract is a rare phenomenon, occurring in 0.3-12% of cases. In more severe forms, the initial presentation may be hydronephrosis or infertility. CASE REPORT We describe the case of a 25-year-old Saudi woman who presented with obstructive urinary tract symptoms and was diagnosed with urinary bladder endometriosis complicated with a right hydronephrosis. After thorough investigations and workups, the management was taken on by a multidisciplinary team approach. CONCLUSIONS This case report shows that hormonal therapy management resulted in a satisfactory outcome contrary to the surgical resection approach that is discussed in many articles.

Pelvic lipomatosis is an uncommon disease with no clear etiology and it occurs secondary to deposition of a large amount of fatty tissue in the pelvis. This deposition causes compression to the rectum, bladder, and venous structures. Because of this compression, various symptoms, such as recurrent urinary infections, dysuria, tenesmus, and constipation, have mostly been reported. However, iliac or superior vena cava thrombosis secondary to vascular compression of pelvic lipomatosis is rare. This report describes a case of pelvic lipomatosis, which was associated with right-sided mild hydronephrosis and portal vein thrombosis.

Rationale: Patients with Down syndrome (DS) have a higher incidence of nonneurogenic neurogenic bladder (NNB) than do normal subjects. Renal failure may occur frequently in NNB patients. Although most of the cases of NNB patients with DS reported to date have been acute renal injuries, we report a patient with DS who was diagnosed late with urinary tract obstruction due to NNB that finally proceeded to end-stage renal disease (ESRD). This case of terminal renal failure is the first such reported case in the world., Patient Concerns: A 35-year-old female patient had visited another hospital for 1 month for abdominal discomfort, nausea, constipation, and palpable mass. Cystic mass in the pelvic cavity, increased BUN, and Cr findings were observed. Residual urine was 1.8 L. She had a history of DS., Diagnoses: Based on computed tomography and urodynamic study, ESRD due to NNB was diagnosed., Interventions: An emergency hemodialysis was performed and a catheter was inserted into the bladder. Transfusion and amlodipine were administered according to the patient's condition. There was no improvement in renal function seen, and so arteriovenous fistula surgery and regular hemodialysis were performed., Outcomes: The patient was discharged from the hospital with a bladder catheter. She was visited on a regular basis for catheter replacement and hemodialysis., Lessons: Patients with DS have lower intelligence than normal people and often do not recognize or complain about inconveniences, even in the presence of urinary symptom. NNB has good prognosis when treated early, but there is a risk of ESRD if the diagnosis and treatment are delayed, as was the case here. Considering that the prevalence of NNB and other urinary tract diseases is high in patients with DS, clinicians need to take careful histories and observe deeply, even if the patient does not mention certain issues.

A 70-year-old man was referred to the Urology Service of our University Hospital for an irregular thickening of the left anterior-lateral urinary bladder wall found in a computed tomography scan following gross haematuria. In particular, the computed tomography scan showed irregularity of the mucosal aspect and an irregular thickening of the bladder wall in close proximity of an inguinal hernia. The computed tomography exam also showed an unusual little fatty seizure in the parietal planes. A magnetic resonance imaging confirmed the thickening in the same area as the hernia with a mainly extraluminal presentation and extension in the perivesical adipose tissue. Cystoscopy did not show alteration of the mucosal surface. Urine cytology showed normal urothelium cells. At the time of the left inguinal hernia repair, the bladder was isolated from the inguinal hernia fat tissue and then opened with median cystotomy. Biopsy of the anterior-lateral bladder wall showed normal urothelium and an abundant component of mature lobules of adipose tissue in the sub-epithelial connective tissue extending among the muscle bundles of muscularis propria, compatible with a diagnosis of lipomatosis, a very rare lesion in the urinary bladder.

Rationale: Pelvic lipomatosis (PL) is a benign disease characterized by overgrowth of adipose tissue in pelvic space. Hydronephrosis and ureterectasis are common complications caused by PL in urinary system. But PL accompanied with upper urinary tract calculi is rare. Also there has been no report of PL with ureteral calculi managed by flexible ureteroscopy (fURS)., Patient Concerns: A 62-year-old man who has been diagnosed of PL was found to have a right-side ureteral calculi by ultrasound in the routine health examination. In addition, the patient has a history of open surgery of uretero-vesical reimplantation in the left side 13 years ago because of heavy hydronephrosis in the left side., Diagnoses: The diagnosis was PL with ureteral calculi in the right side and heavy hydronephrosis in the left side., Interventions: FURS was performed to remove the right ureteral calculi., Outcomes: A follow-up of 1 year showed that there was no progression of the hydronephrosis in right side and serum creatinine was stable., Lessons: FURS is a suitable option for the upper urinary tract calculi accompanied with anatomical abnormality such as horseshoe kidney, pelvic ectopic kidney and so on. For patient of PL accompanied with upper urinary tract calculi, fURS is suitable and indicated.

Objectives: Correction of structural urologic disorders and optimization of emptying and storage function of the bladder should be achieved before renal transplant in patients with abnormal urinary bladders to protect the new transplanted kidney. The aim of this study was to determine the outcomes of renal transplant among the differently treated abnormal bladder patients., Materials and Methods: This was a retrospective study of 30 renal transplant recipients with abnormal bladders who were divided into 2 groups based on abnormal bladder management. Group A included 12 patients who required surgical procedures for their bladder, including 6 with augmentation cystoplasty, 1 with Mitrofanoff procedure, 2 with ileal conduit, 1 with vesicostomy, and 2 who required artificial urinary sphincter. Group B included 18 patients who were treated with oral anticholinergics or beta-3 sympathomimetic drugs, clean intermittent catheterization, suprapubic catheterization, or a combination of these options. Graft function, survival, and complications were compared between both groups., Results: Mean estimated glomerular filtration rates at 1, 3, and 5 years were higher in group A than in group B but not statistically significant. We also found no significant differences in graft survival between the 2 groups. Among all postoperative complications, only incidence of wound infection was significantly higher in group A than in group B (33% vs 5%; P = .04)., Conclusions: The options of abnormal bladder treatment (either by surgical procedures or other methods of treatment) did not have an impact on graft outcome after renal transplant as long as a safe and suitable bladder was achieved.

We report a patient who developed urinary retention due to the presence of necrotic tissues in the bladder 5 months after kidney transplantation. The patient was a 47-year-old female who had been diagnosed with immunoglobulin A nephropathy. She requested to receive a living-donor kidney transplant from her husband, and was referred to our hospital. Given that the patient had anuria preoperatively, her bladder capacity was presumed to have decreased following the transplantation. There were no events regarding vascular anastomosis during the surgery. However, since ureteroneocystostomy was difficult to perform due to the thinning of the bladder wall, the recipient's own ureter was anastomosed to the ureter of the transplanted kidney. Since the patient had difficulty voiding soon after the indwelling urinary catheter was removed, clean intermittent self-catheterization was initiated. Abdominal computed tomography revealed perforation of the bladder and extravesical urinary leakage on postoperative day 15. An indwelling urinary catheter was reinserted as conservative treatment. We removed the indwelling urinary catheter on postoperative day 25. The patient was discharged on postoperative day 30. Five months after transplantation, the patient suddenly developed urinary retention. Cystoscopy revealed some tissue hanging from the anterior wall of the bladder. The tissue was removed, and her voiding function improved. On pathology, the tissue was found to be non-specific necrotic tissue. This finding suggested that the necrotic tissue had caused urinary retention 5 months after transplantation. The symptoms of urinary retention markedly improved after the treatment.
