Tumour-to-tumour metastases (TTM) are a rare phenomenon in which a primary tumour has metastasised within another distant primary tumour. We present the case of a 63-year-old female who presented with right-sided breast cancer. An incidental left-sided renal mass was detected on staging CT of the thorax, abdomen, and pelvis (CT-TAP). The patient had no evidence of metastases below the diaphragm. Histology following a radical left nephrectomy revealed metastatic breast cancer within a renal cell carcinoma (RCC). The patient underwent chemotherapy and surgery for right-sided breast cancer. Follow-up imaging demonstrated the metastatic spread of the breast cancer. This is an unusual case of TTM from breast to an initially occult RCC primary.

Purpose: To address the pattern of urodynamic findings in diabetic patients with lower urinary tract symptoms (LUTS), comparing short-standing and long-standing type 2 diabetes mellitus (T2DM). Methods: A prospective study was conducted on 50 patients pre- senting with LUTS and a concurrent diagnosis of T2DM, between February 2016 and May 2018. Patients were classified and evaluated according to the duration of diabetes into two groups: short-standing DM (< 15 years, n = 31), and long-standing DM (≥ 15 years, n = 19) groups. The impact of LUTS and quality of life were assessed in female patients using ICIQ-FLUTS and male patients using ICIQ-MLUTS. Results: A total of 50 patients were included in the study. The mean duration of T2DM was 10 ± 0.7 years. The mean age was 56.3 ± 1.2 years, and the mean HbA1c was 7.5 ± 1.2%. Urodynamic evaluation detected significantly higher detrusor overactivity (DO) and increased bladder sensation with the short-standing DM group (35.5 vs. 15.8%, p = 0.01 and 32.3 vs. 5.3%, p = 0.01, respectively). Comparatively, weak, or absent detrusor contractility were more frequent in patients with long-standing DM (52% and 26% respectively p = 0.01). As expected, overflow incontinence and straining during voiding were significantly higher in the long-standing DM group (p = 0.04 and p = 0.03, respectively). Surprisingly, there was no significant correlation between patients presenting with urgency in their voiding diary (subjective) and urodynamic detection of DO (p = 0.07). Conclusions: There are different patterns in urodynamic charac- terizations of T2DM. Patients with short-standing DM present more commonly with storage symptoms and detrusor overactivity on urodynamics. Contrastingly, patients with long-standing DM present more frequently with voiding symptoms and detrusor underactivity on urodynamics. Thus, screening for an underactive bladder is advisable in patients with long-standing T2DM.
