Summary
Partial nephrectomy is preferred for obstructed duplicated kidneys, showing no significant renal function loss and a lower reoperation rate compared to upper pole salvage procedures.
Area of Science:
- Pediatric Urology
- Nephrology
- Surgical Outcomes
Background:
- Duplicated kidneys with upper pole obstruction are a common congenital anomaly in children.
- Management decisions impact differential renal function and long-term outcomes.
Purpose of the Study:
- To compare differential renal function after upper pole salvage versus partial nephrectomy in children with obstructed duplicated kidneys.
- To evaluate postoperative complications and reoperation rates for both surgical approaches.
Main Methods:
- Retrospective review of 46 children with unilateral obstructed duplicated kidneys (1988-1995).
- Comparison of upper pole salvage (ureteropyelostomy/ureteroureterostomy) versus partial nephrectomy.
- Assessment of differential renal function via nuclear renography and analysis of complication/reoperation rates.
Main Results:
- Partial nephrectomy group (31 patients) had a 4% reoperation rate and minimal change in renal function (-1.25%).
- Upper pole salvage group (12 patients) had a 25% reoperation rate and a slight gain in renal function (2.25%).
- No statistically significant difference in relative renal function between the two groups was observed.
Conclusions:
- Partial nephrectomy offers comparable renal function preservation with a significantly lower reoperation rate.
- Upper pole salvage procedures did not demonstrate a significant gain in relative renal function.
- Partial nephrectomy is recommended as the preferred treatment for most cases of obstructed duplicated kidneys.

01:27Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage.
