INTRODUCTION:
Conservative kidney management (CKM) is a recognised treatment option for selected patients with chronic kidney disease stage 5 (CKD G5), but prognostic indicators for mortality and optimal timing for palliative care transition remain uncertain.
METHOD:
This is a single-centre, prospective cohort study of CKD G5 patients who opted for CKM, conducted between April 2021 and September 2024, with longitudinal monitoring of Edmonton Symptom Assessment System Revised: Renal; Palliative Perfor-mance Scale (PPS); Resources Utilisation Group.Activities of Daily Living (RUG-ADL) scale; Clinical Frailty Score; Karnofsky Performance Score; and clinical and laboratory data. Primary outcomes included identifying baseline mortality predictors and validating the PPS for survival estimation. Cox proportional hazards models were used to identify independent predictors of mortality.
RESULTS:
Among 109 patients (mean age 79.8±7.3 years, 64.2% female), 62 (56.9%) died during follow-up. Multivariate analysis identified baseline estimated glomerular filtration rate (eGFR) (hazard ratio [HR] 1.32, 95% confidence interval [CI] 1.08.1.68, P<0.01) and serum albumin (HR 1.24, 95% CI 1.08.1.43, P<0.01) as predictors of 1-year mortality. Median survival varied by eGFR: 3.0 months (95% CI 0.6.2) for eGFR .5 mL/min/1.73 m2, 13.0 months (95% CI 9.1.16.9) for eGFR 6.10 mL/ min/1.73 m2, and 20.0 months (95% CI 16.5.23.5) for eGFR >10 mL/min/1.73 m2 (P<0.01). Subsequent PPS correlated strongly with survival, with median survival of 1.8 months for PPS <50, 5.3 months for PPS 50.60, and 7.9 months for PPS 70.80 (P=0.03).
CONCLUSION
Baseline eGFR and serum albumin predict 1-year mortality in CKM patients. PPS offers a practical tool for identifying patients requiring palliative care transition, supporting personalised care pathways and timely integration of palliative care.

Myeloid sarcoma (MS) is a rare extramedullary myeloid tumour. It has been reported in various
sites, including lymph node, bone, skin, soft tissue, various organs and the CNS. It may precede
or occur concurrently with acute myeloid leukemia. Urinary bladder involvement is extremely
uncommon. We report a 70-year-old female who had MS of the urinary bladder, presented with
frank and persistent hematuria associated with lower abdominal pain. She subsequently had tumour
seeding in the abdominal skin via percutaneous suprapubic catheter. Tumours from both the urinary
bladder and skin showed immature cells that were immunoreactive toward LCA (focal), MPO (strong),
CD99 (weak) and CD117 (weak). Summary of cases in the literature is presented. The potential of
its misdiagnosis and the useful markers for the diagnosis of MS are discussed

Ketamine can be abused as a recreational drug, and there has been a recent surge in its
usage. The effects of ketamine on the urinary system were unknown until the recent publication
of a few case reports. Many doctors are still unaware of this new clinical entity, termed ketamineassociated
ulcerative cystitis. We report a case that we encountered and discuss the diagnosis and
disease management in addition to a review of the literature.
