Two main sites of urine flow obstruction in the upper urinary tract are located at the pelviureteric and vesicoureteric junctions, both of which result in urinary tract dilatation. With current antenatal ultrasound screening, most patients are identified before birth, and 10–30% of infants with antenatal hydronephrosis are found to have pelviureteric junction obstruction, and 5–10% vesicoureteric junction obstruction/megaureter. In addition, a megaureter can also be based on urine reflux, even in combination with obstruction, or be a non-refluxing non-obstructed megaureter. In case of obstruction, surgery may be indicated, but identifying cases that need to be operated on is challenging and no good marker to assist in this differentiation is available yet.

Surgery in patients with a neurogenic bladder aims at protecting the upper urinary tract while maximizing the patient’s continence status. It is carried out when other modalities, such as medication and minimal invasive procedures, fail to produce optimal results. Factors to consider are the patients’ level and completeness of the neurologic injury, gender, habitus, dexterity and cognitive functions as well as renal function, and bowel availability. Surgery of the neurogenic lower urinary tract (LUT) aims to create a low pressure and continent system when possible, mainly achieved by the use of bowel segments. The incorporation of bowel into the LUT is associated with potential complications that make lifelong surveillance obligatory. Recently, technologic innovations have changed the way LUT reconstruction could be carried out. Robotic surgery is now a legitimate option for LUT reconstruction in both adults and pediatric patients. In the future, regenerative medicine could provide organs that would obviate the need for an intraperitoneal surgery and bowel manipulation with its associated complications. However, currently, this technology has not produced consistent results, and its utilization is not widespread. In this review, we discuss the available surgical treatment options of patients with a neurogenic bladder. This review contains 5 figures, 1 table, and 56 references. Key Words: bladder augmentation, bladder neck closure, neurogenic bladder, neuromodulation, sling, sphincterotomy, surgery, treatment
