Review
While robotic surgery has shown clear utility and advantages in the adult population, its role in pediatrics remains controversial. Pediatric-sized robotic instruments and equipment are not readily available yet, so certain modifications can be made in order to make robotic surgery successful in children. While the cost of robotic surgery remains high compared to open procedures, patients experience greater satisfaction and quality of life with robotic surgery. Robotic pyeloplasty is a standard of care in older children, and has even been performed in infants and re-do surgery. Other robotic procedures performed in children include heminephroureterectomy, ureteroureterostomy, ureteral reimplantation, urachal cyst excision, bladder diverticulectomy, and bladder reconstructive procedures such as augmentation, appendicovesicostomy, antegrade continence enema, bladder neck reconstruction and sling, as well as other procedures. Robotic surgery has also been used in oncologic cases such as partial nephrectomy and retroperitoneal lymph node dissection. Future improvements in technology with production of pediatric-sized robotic instruments, along with increases in robotic-trained pediatric urologists and surgeon experience along each's learning curve, will help to further advance the field of robotic surgery in pediatric urology.

An allantoic cyst is a rare malformation with a frequency of 3 in 1,000,000 that may be seen antenatally by ultrasound assessment when the connection between the cloaca (future bladder) and the allantois fails to regress. A patent urachus that presents as a cyst (allantoic) is usually considered not to be associated with chromosomal abnormalities, but if it is not repaired after birth this leads to complications such as urinary tract infections and stone formation. We present a case of a fetus diagnosed with allantoic cyst at the first trimester ultrasound assessment at 12 weeks gestation. The follow up scans showed a decrease in size of the allantoic cyst with no other obvious major defects and, when invasive testing (amniocentesis with microarray analysis) was performed, a rare microdeletion, 1q21.1q21.2 was identified (1.82 Mb deletion).

CASE PRESENTATION
A seven-year-old male presented to the pediatric emergency department with one day of abdominal pain. His physical exam was significant for rebound, guarding, and tenderness in the right lower quadrant, and his labs demonstrated a leukocytosis. Both a point-of-care ultrasound and radiology-performed ultrasound were concerning for acute appendicitis with a periappendiceal abscess, but on emergent laparoscopy the patient was found to have an infected urachal cyst.
DISCUSSION
Infected urachal remnants are a rare but important cause of pediatric abdominal pain. In this case, inflammation surrounding the patient's midline urachal cyst triggered a serositis that involved the appendix and pulled the cyst to the right. This created a clinical and radiologic presentation similar to appendicitis. This atypical presentation of an already rare anomaly highlights the importance of maintaining a broad differential during the work-up of pediatric abdominal pain.

International Journal of Urology :... Jul 2000We report on an extremely rare case of urachal tuberculosis that was confirmed using a polymerase chain reaction test of paraffin-embedded material.
BACKGROUND
We report on an extremely rare case of urachal tuberculosis that was confirmed using a polymerase chain reaction test of paraffin-embedded material.
METHODS/RESULTS
A 62-year-old man presented with pollakiuria. With a diagnosis of urachal abscess, the patient underwent en bloc resection of the cystic mass. A bacterial culture test of the content showed no organism. The histopathologic findings suggested urachal tuberculosis. The AMPLICOR polymerase chain reaction test by using paraffin-embedded sections revealed the existence of Mycobacterium tuberculosis in the resected tissue. The only positive finding in systemic screening examinations for tuberculosis was old tuberculosis scars in the upper right lung. It was supposed that hematogeneous spreading from the lung lesion may result in urachal tuberculosis after a long latent period.
CONCLUSIONS
Although urachal tuberculosis is an extremely rare condition, tuberculosis must always be kept in mind when observing any infectious diseases.

Combination of posterior urethral valves and urachus remnants has been described as rare occurrence. We report a case of a baby boy with normal antenatal scans, in whom the presence of large urachal cyst and posterior urethral valves causing high pressure bladder and chronic kidney disease was found. The patient underwent ablation of posterior urethral valves at 23 days of life and urachal cyst removal at age of 4 and a half months.

We report the case of a 16-year-old girl who complained of stomach discomfort. She's been on medical therapy for roughly 6 months after being diagnosed with Crohn's disease. Magnetic resonance enterography confirmed the diagnosis of an infected urachal cyst, and she eventually had surgery. The removed material had a significant chronic inflammatory and foreign body type granulomatous response, according to histology. Because urachal cyst is an uncommon disease, early identification requires a high level of suspicion, and urachal cyst should be included in the differential diagnosis.

Review
The urachus is a canal between the allantois and the early fetal bladder. Urachal carcinoma is a rare and aggressive type of bladder cancer. This cancer usually presents at an advanced stage. We report a 70-year-old patient with malignant transformation of urachal cyst several years later. The patient was treated with partial cystectomy and adjuvant radiotherapy. A review of the published literature is also presented.

INTRODUCTION
Urachus is an embryonic remnant that usually involutes before birth. Abnormal persistence of this structure gives embryologic malformation like an urachal cyst. Infection or malignancy degeneration can complicated it.
CASE PRESENTATION
Case 1: We report 20 years old female patient consulted with acute abdominal pain. Clinical examination showed fever and infra-umbilical tender mass. The abdominal Computerized Tomography showed pelvic mass between umbilicus and bladder. The open laparotomy found infra-abdominal semi-solid mass. A complete resection was done and histological exam confirmed infected urachal cyst. Case 2: A 19 years old male patient presented with abdominal pain and fever. Physical examination found tenderness in lower abdomen. Biology revealed leukocytosis, and Ultrasonography found a heterogeneous infra-umbilical mass. Surgical exploration by mini-laparotomy found an abscess urachal cyst that is confirm by histological exam after complete resection.
CLINICAL DISCUSSION
Urachal cyst in adult patient is rare. Clinical symptoms without complications are insignificant. Because of malignancy risk, adult urachal cyst are managed by surgery.
CONCLUSION
Infection cyst is the most common complication of urachal cyst. Complete resection is recommended because of malignancy degeneration risk.

The urachus is a tubular structure that is apparent on the third week and connects the ventral cloaca to the yolk sac, as a progression from the allantois. Following the normal regression procedure, the urachus remains as the median umbilical ligament. Urachal remnants are present in 1.03% of paediatric patients while in 92.5% of cases represent incidental findings. Urachal anomalies are classified in four types as patent urachus (50-52%), urachal sinus (15%), urachal cyst (30%) and urachal diverticulum (3-5%). Ultrasound scan is the most commonly performed diagnostic imaging study. In case of symptomatic urachal remnants, surgical excision is indicated. Asymptomatic urachal remnants that are diagnosed at the neonatal period or early infancy should be watched up to 6 months of age, as they are likely to resolve. In persistent or symptomatic urachal remnants there is a risk of inflammation or even malignancy development, therefore we believe that there is indication for preventive surgical excision that may be performed either open or laparoscopically or by robot-assisted laparoscopy.
