First-line treatments
Conservative Watchful Waiting with Imaging
Regular monitoring with ultrasound and voiding cystourethrogram to assess ureteral dilation and renal function over time. Many mild cases remain stable without intervention.
Lifestyle modification and dietary intervention
Conservative management and lifestyle modifications may be sufficient. Monitor symptoms.
Diagnostic Urodynamic Studies
Comprehensive evaluation of urinary tract function including assessment of obstruction severity and bladder dynamics. Helps determine if intervention is necessary and guides treatment planning.
Additional treatment options
Ureteral Reimplantation Surgery
Surgical correction to restructure the ureterovesical junction when conservative measures fail or significant obstruction is documented. Modern minimally invasive techniques reduce recovery time.
surgicalProphylactic Antibiotic Therapy
Low-dose antibiotic prophylaxis may be considered in cases with recurrent urinary tract infections, though routine use is debated. Aims to prevent symptomatic infections while awaiting spontaneous resolution.
