RESUMO
BACKGROUND: Bladder duplication is a rare congenital lower urinary tract anomaly disease characterized by the presence of two bladders, possibly with duplication of the urethra. This disease is rarely reported in cats. The clinical symptoms are commonly occult, with increased difficulty in making a definitive diagnosis, especially if there is no obvious urethral duplication. The diagnosis is typically based on radiographs and ultrasound, with computer tomography serving as a more advanced imaging diagnostic modality. Cases of duplicated bladders with accessory tubular tissues are even scarcer in both human and veterinary medicine. CASE PRESENTATION: A 6-year-old male neutered cat was brought to the hospital because of vomiting and constipation. Cystography revealed increased soft tissue density of a fusiform structure in the lower middle abdomen. The purulent-filled cavitary structure and the accessory tubular structure were removed via surgery, and histopathological examination confirmed a double bladder with attached accessory tubular tissue. After antibiotic treatment, the cat recovered uneventfully. CONCLUSION: This is the first case of bladder duplication in China and the first case of feline bladder duplication with tubular structure attachment in the world. This information will provide a reference for the diagnosis and treatment of similar cases in the future.

Bladder duplication is an extremely rare congenital anomaly of the urinary system that is more frequent in boys; the literature is limited to case reports and case series. We describe two cases of bladder duplication in two infant girls with an uncommon variant of complete sagittal septum not included in the Abrahamson classification. The diagnosis was made using magnetic resonance urography, combining excellent anatomical information and static and dynamic evaluation of the urinary tract. The diagnostic information provided by MR-urography was confirmed on surgical exploration. These cases provide an opportunity for paediatric radiologists and urologists to learn more about bladder duplication and improve their diagnosis of this rare condition.

The duplication of the gall bladder (GB) is unusual biliary anatomy that can be encountered during cholecystectomy and can create intraoperative confusion if missed on pre-operative imaging. Here, we describe a case of duplication of GB in a young female, which was detected during laparoscopic cholecystectomy as an operative surprise. Laparoscopic cholecystectomy was done successfully with the removal of both the GBs. She was discharged uneventfully and remained symptom-free at a 6-month follow-up.
RESUMO
A Type II choledochal cyst arising from the right hepatic duct may mimic a gall bladder duplication. Both are rare and may not get differentiated before operative exploration. While a magnetic resonance cholangiopancreatography (MRCP) may be helpful, laparoscopy may be the final tool for evaluation and effective surgical treatment. We report such a case of a 22-year-old male whose MRCP was suggestive of a cystic lesion in the gall bladder fossa and was taken up for surgery with a pre-operative diagnosis of gall bladder duplication with a single cystic duct. He underwent elective laparoscopic evaluation, mobilisation, discerning of anatomy and diagnosis, excision of cyst and concomitant cholecystectomy. This case highlights that these two rare entities can mimic each other on imaging; however, a laparoscopic approach serves the dual purpose of diagnosing and treating this unique pathoanatomical entity.
RESUMO
Anorectal malformations are a common congenital anomaly, while bladder duplication is rare. Bladder duplications are classified as complete or incomplete and sagittal or coronal. We present a rare case of coronal complete bladder duplication with rectoprostatic fistula to the blind ending prostatic urethra of the duplicated bladder.

A female kitten presented for chronic, intermittent, antibiotic-responsive urinary incontinence and chronic kidney disease. Abdominal ultrasound identified bilateral pelvic/ureteral dilation and three closely apposed thin-walled fluid-filled structures in the caudal abdomen, extending toward the pelvic inlet. Excretory urography and negative contrast cystography identified contrast medium accumulation from the dilated ureters into two tubular soft tissue masses of the caudal abdomen, with subsequent gradual filling of a more cranially located urinary bladder. A retrograde vaginocystourethrogram identified a normal uterus, normal vagina, and a single urethra continuous with the cranially located urinary bladder. Antemortem diagnosis was suspicious for bilateral ectopic ureteroceles. Postmortem diagnosis, 35 months following initial presentation, determined the fluid-filled masses to have abundant smooth muscle in the wall, including a muscularis mucosa connected by a common ostium, consistent with urinary bladder duplication. Urinary bladder duplication should be included as a differential diagnosis in cats with these clinical and imaging characteristics. In this case, differentiation of ectopic ureterocele from urinary bladder duplication required histological confirmation.

Bladder duplication and congenital bladder diverticulum are rare anomalies. We described two boys with rare bladder anomalies found on prenatal ultrasounds. Postnatal investigations and surgical findings confirmed these bladder anomalies. The malformation was associated with other system anomalies. This report of pre- and postnatal imaging with surgical correlation contributes to our understanding about these rare bladder anomalies.
RESUMO
Bladder duplication (BD) is a rare malformation that is often associated to other anomalies. We report a newborn diagnosed with BD in the sagittal plane, associated to persistent urogenital sinus (UGS), given the opening of the vagina immediately below the bladder neck. It is the fourth time this association is reported. Surgical repair was made: both bladders were joined, the common channel was left as urethra and the vagina was descended with a vaginoplasty with an intestinal segment. She also presented an anterior anus, that required posterior mobilization. The patient is currently 3 years old with good sphincter control.
RESUMO
INTRODUCTION: The bladder-Exstrophy-Epispadias complex (BEEC) contains a wide spectrum of congenital malformations. A treatment naïve refugee was referred to our center with what was identified as BEEC. MATERIALS AND METHODS: A 27-year-old female patient was referred for total incontinence since birth by the general practitioner from the refugee center. An exstrophic bladder with blind ending ureteral orifices and a second non-exstrophic bladder with two orthotopic ureters was identified, demonstrating the bladder duplication in the sagittal plane. Laparotomy was performed, dissecting the exstrophic bladder plate caudally and using it as a ventral onlay to augment the non-exstrophic bladder. A Mitchell-type bladder neck reconstruction was performed with an autologous fascia sling around the bladder neck to obtain continence. As the patient had never voluntarily voided, chances of spontaneous voiding after surgery were low. Therefore creation of a continent Mitrofanoff-type vesicostomy was additionally realized and genital reconstruction was achieved. RESULTS: 12 months post operatively, the patient was completely continent, had a bladder capacity of 250 ml, and performed self-catheterization 5 times a day. No post-operative complications were observed. CONCLUSION: Admission of political refugees can implicate challenging surgeries for congenital malformations in adults, such as BEEC. This demonstrates the importance of multidisciplinary transitional care.

Background: Exstrophy variants are well described urologic anomalies. They are characterized by atypical anatomical and physical findings than those found in patients with classic bladder exstrophy and epispadias malformation. The combination of these anomalies with duplicated phallus is a rare occurrence. Here we present a neonate with a rare form of exstrophy variant associated with penile duplication. Case Summary: One day old male neonate who was born at term was admitted to our neonatal intensive care unit. He had lower abdominal wall defect and open bladder plate with no visible ureteric orifices. There were two completely separate phalluses with penopubic epispadias and urethral orifices draining urine. Both testes were descended. Abdominopelvic ultrasound showed normal upper urinary tract. He was prepared and operated with intra operative finding of complete bladder duplication in the sagittal plane and each bladder has its own ureter. The open bladder plate which had no connection with both ureters and urethras was excised. The pubic symphysis was approximated without osteotomy and abdominal wall was closed. He was immobilized with mummy wrap. He had uneventful post-operative course and was discharged on the 7th post-operative day. He was evaluated on the 3rd month post operatively and he was thriving well with no complications. Conclusion: The occurrence of a triplicated bladder along with diphallia is an exceptionally rare urologic anomaly. As a number of variations are possible in this spectrum, the management of neonates with this anomaly should be individualized.
RESUMO
OBJECTIVES: Robinow syndrome is a very rare syndrome characterized by short stature, extremity deformities, costovertebral abnormalities, renal/external genital malformations, and fetal facial appearance. It might be inherited by either autosomal dominant or severe recessive form. Diagnosis is generally established by the aid of genetic mutation and phenotypic findings. The urogenital component of the disease frequently presents with microgenitalia such as micropenis and/or cryptorchidism. METHODS: Herein, a four-year-old boy with Robinow syndrome accompanied by incomplete bladder duplication is discussed. RESULTS: The duplication in the bladder was screened by cystoscopy and corrective surgery was performed. CONCLUSIONS: This rare manifestation is the first for urological findings of Robinow syndrome in literature.

BACKGROUND: Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a congenital disorder characterized by underdevelopment of the uterus and vagina. CASE: A 4-year-old girl was declared dead on arrival to the hospital with a history of chronic constipation since birth. Postmortem examination showed Müllerian remnants attached to abnormal fibrous tissue. The fibrous tissue extended from the descending colon to the rectum and connected to a urinary bladder duplication cyst. The fibrous tissue formed into a constricted band around the rectum. The cause of death was Streptococcus pyogenes sepsis with intestinal obstruction secondary to the rectal fibrotic band and urinary bladder duplication cyst. SUMMARY AND CONCLUSION: MRKH syndrome is a rare congenital disorder, and the malformations rarely cause death. We describe the features of abnormal fibrous tissue and urinary bladder duplication cyst in a patient with MRKH syndrome.

In a male neonate with bilateral hydroureteronephrosis, the most common surgical diagnosis is posterior urethral valves. This case report describes a male infant with the same presentation, but caused by a very uncommon congenital anomaly. The summation of different imaging modalities allowed a multidisciplinary team of colleagues to define the anatomy: bilateral duplex kidneys draining into separate urinary bladders. Only one of the bladders had an outlet, hence the obstructive uropathy to the right kidney led to total loss of function. The distended tortuous ureters produced a mass effect at presentation. This case acts as a reminder that complex congenital anomalies can mimic the presentation of more common conditions, and that they often require input from various specialists to diagnose the condition and guide its management.
RESUMO
The Exstrophy - Epispadias Complex (EEC) is a spectrum of rare congenital malformations involving the urinary, genital and musculoskeletal systems. We present an atypical or variant case of EEC in which a bladder plate is found involving a small omphalocele, separated pubic bones and bladder and urethral duplication. The treatment had a favorable outcome, with bladder control and the child voiding normally. Perhaps the best accepted embryonic theory to explain exstrophy and its variants should be reviewed as it fails to satisfactorily explain the alterations we found.
RESUMO
Bladder duplication is an extremely rare congenital urinary tract malformation that is often discovered incidentally. Here, we report a case of incomplete bladder duplication diagnosed by SPECT/CT in a 65-y-old man with lung cancer. Compared with the results of whole-body planar bone scintigraphy, this SPECT/CT finding caused the diagnosis to be revised in this patient with suspected bone metastases. To our knowledge, this is the first documented case of incomplete bladder duplication discovered by SPECT/CT.

INTRODUCTION: Choledochal cyst (CC) is an uncommon congenital disease of the biliary tract. There are five main types of CC with several recognized sub-types. However, occasional variants with a difficulty in diagnosis and management do occur. PRESENTATION OF THE CASE: We report a case of a nine years old female child diagnosed with CC who presented with right quadrant abdominal pain with unremarkable physical findings. Investigation using abdominal CT scan suggested type II choledochal cyst. The intraoperative finding revealed an unusual site of the cyst that is at the confluence of common hepatic duct (CHD) posteriorly. The cyst was successfully excised and the child is doing well on her follow ups. DISCUSSION: In the management of choledochal cyst the anatomy should be clearly defined with detailed investigations like Abdominal CT Scan or cholangiography before surgical excision as abnormal variants which usually do not fit into the known classification types and subtypes. This might confuse with other differentials like gall bladder duplication. Surgical excision is the gold standard management option. CONCLUSION: This case report will alert surgeons that there are different anatomic variant of choledochal cysts out of the known classifications and with meticulous dissection will help proper excision and avoid unnecessary complications.
RESUMO
Complete diphallia, a rare urogenital congenital anomaly in which a male is born with two fully formed phalluses, occurs in one out of every five to six million live births. The condition is characterized by two separate phalluses, each of which comprise a pair of corpora cavernosa and one corpus spongiosum with an orthotopic urethra. Approximately 100 cases have been reported worldwide, and it is thought that each case is unique. This article discusses diphallia, urethral duplication, and bladder duplication and concludes with a case study involving a three-year-old male born to consanguineous parents from a small, remote community in Ecuador who underwent surgery for correction of a complete coronal penile and bladder duplication. After consultation, the patient was scheduled for a right penectomy and cystoplasty.

OBJECTIVE: Complete bladder duplication is a male predominant rare congenital malformation usually diagnosed at birth. Owing to the rarity of this anomaly, only few reports have discussed the surgical approach for this condition, with the open approach for excision being the most common. We hereby present a video of a laparoscopic resection of complete bladder and urethral duplication in a 1-year-old male. METHODS: The patient presented to our clinic with a red mucosal tissue protruding from a cutaneous opening at the dorsal base of the penis that has been present from birth. A normally located and functioning bladder and urethra were present. During work-up, a cystic mass located above the bladder was discovered in imaging examinations. No other anomalies were found. After a shared decision process, we performed a laparoscopic transperitoneal bladder duplication excision during which the accessory urethra and duplicated bladder were removed with preservation of the adjacent normal urethra. The patient had an uneventful recovery with excellent cosmetic results. CONCLUSION: The minimally invasive approach can be utilized for treatment of complex urinary anomalies in young children.

Cloacal exstrophy is the most severe type of anorectal malformations that belongs to the bladder-exstrophy-epispadias complex of genitourinary malformations. Interestingly, its variant, the covered cloacal exstrophy, is often missed. The clinical findings of this variant may include an imperforate anus, low lying umbilicus, thick pubic bone, and pubic diastasis but with an intact abdominal wall. We present an interesting case of covered cloacal exstrophy with a side-by-side duplicated bladder and discuss important considerations for the time of colostomy creation in the newborn period.
RESUMO
A case of complete bladder duplication with urethra duplication, diphallus, anorectal malformation and rightsided renal agensis with ipsilateral gonadal agenesisis was reported because of its rarity. Possible deranged embryology resulting in these anomalies has been reviewed with relevant hypothesis. The patient underwent several investigations and undergoing multistage surgical intervention.
