The scenario that leads to the use of indwelling ureteral stents is closely associated with non-dilated obstructive uropathy. This condition occurs when there's an obstruction in the urinary tract that prevents urine from flowing freely from the kidney to the bladder, but without significant dilation of the urinary collecting system initially observed on imaging studies.

Indwelling ureteral stents serve several important purposes in this context. They help to relieve the obstruction by providing a pathway for urine to bypass the blockage, thus preventing complications such as kidney damage or infection. Stents can maintain urine flow, allowing the kidney to continue functioning while the underlying cause of the obstruction is addressed, which may involve further interventions.

In contrast, other provided scenarios do not typically warrant the placement of indwelling ureteral stents. A bladder infection, for instance, is primarily treated with antibiotics and may require different therapeutic strategies rather than mechanical support for urine drainage. Diabetes mellitus can lead to various complications affecting the urinary system, but it does not inherently indicate a need for stent placement unless accompanied by obstructive uropathy. Overactive bladder relates more to bladder function and control rather than an obstruction in urinary flow, so stents are not indicated in this case either
