Correction - Impact of chemoradiotherapy for bladder cancer on pre-existing hydronephrosis and development of new hydronephrosis

Q: What was corrected in the article?

Caption text from Figs. 1 and 5 was mistakenly captured as part of the main text due to a typesetting mistake. The notice provides the corrected caption wording.

Q: What does the corrected Fig. 1 caption describe?

It describes how patients with pre-existing hydronephrosis are analyzed for nephron-sparing and bladder-sparing perspectives, including components and thresholds related to eGFR and kidney atrophy.

Q: How should patients be counseled according to the corrected Fig. 5 caption?

Patients should be counseled on both bladder-sparing and nephron-sparing approaches; when CRT is considered, a DMSA scan is used to assess relative renal function, guiding whether CRT can proceed without drainage and when drainage or cystectomy may be needed.

Correction notice for a Radiation Oncology article addressing a typesetting error in figure captions. Portions of captions from Figs. 1 and 5 were inadvertently included in the main text. The corrected caption text clarifies analyses for nephron-sparing and bladder-sparing perspectives in patients with pre-existing hydronephrosis, including criteria using eGFR thresholds and kidney atrophy. It also specifies counseling and management guidance for chemoradiotherapy, including the role of DMSA scan, relative hydronephrotic kidney function thresholds, and when drainage or cystectomy should be recommended.

The following text should have been captured as part of the caption of Fig. 1, instead of as part of the main text: All patients with pre-existing hydronephrosis are analyzed for the nephron-sparing and for the bladder-sparing perspectives. Drainage, cystectomy and local MIBC recurrence at any location in the bladder are components of both COs. Additional components in the nephronsparing CO are (1) a decrease in eGFR of ≥ 1 category and (2) the development of an atrophic kidney. The additional component of the bladder-sparing perspective CO is an eGFR < 30 ml/min/1.73 m2. If any component of the perspective’s CO occurred in a patient, CRT was regarded asan unpreferred treatment choice in that patient. The following text should have been captured as part of the caption of Fig. 5, instead of as part of the main text: Patients should be counselled on both bladder-sparing and nephron-sparing treatment approaches. In cases where the patient expresses a preference for chemoradiotherapy (CRT) and meets the necessary criteria, adimercaptosuccinic acid (DMSA) scan should be conducted to evaluate the relative function of the hydronephrotic kidney. In cases where the relative function is less than 10%, CRT can be performed without the need for drainage. However, it is imperative to discuss the risks of complications, such as infection, with the patient. In instances where the relative function is 10% or greater, The original article can be found online at [https://doi.org/10.1186/s1](https://doi.org/10.1186/s1)[ ](https://doi.org/10.1186/s1)[3014-025-02678-9](3014-025-02678-9.)[.](3014-025-02678-9.) *Correspondence: Marinka J.
