Cancer is a major health problem with a significant impact on society and healthcare systems. In 2018, approximately 18.1 million cases of cancer were diagnosed and 9.6 million deaths were documented. Urological cancers account for 12.9% of new cases recorded and 8% of deaths due to cancer worldwide. The latest cancer registries covering the Gulf Cooperation Council (GCC) countries report that 4078 cases of renal cell carcinoma were diagnosed from 1998 to 2012. Urological cancers comprised 9.4% of all cases with an incidence rate of 16.1% in males and 3.2% in females.All renal cancer cases documented in Salmaniya Medical Complex (SMC) from 2014 to 2018 were reviewed. Data collected for all patients from the electronic health record system included age at diagnosis, gender, laterality of cancer (where applicable), histological type, and TNM (tumor, node, metastasis) classification and staging. Furthermore, World Health Organization (WHO) grade and data were collected for kidney cancer cases. Statistical analysis was carried out using Statistical Package for the Social Sciences (SPSS) version 23 (IBM Corp, Armonk, NY).From 2014 to 2018, there were 65 documented cases of kidney cancer with an average caseload of 13 cases per year. The mean age at diagnosis was 57.6 years. Clear cell carcinoma was the most common histological subtype (37.5%). Stage 1 was the most common stage at diagnosis (35.4%) and the age-standardized mortality rate for males and females were 4.59 and 4.58 in 100,000, respectively. Kidney cancer is a urological malignancy that can pose a burden on both the patient and the healthcare system. There should be a national effort to better understand the etiology and epidemiology of this disease entity with regard to our population. Such efforts would make data regarding diagnosis, management, and follow-up more accessible and would add positively to our healthcare system.

An ectopic kidney is a rare developmental anomaly in which the kidney can be pelvic, iliac, abdominal, and thoracic, and affected patients are more prone to conditions such as reflux, pelvic ureteric junction (PUJ) obstruction, hydronephrosis, nephrolithiasis, and even renal failure than patients with normally structured kidneys. In this case, we present a 43-year-old male who is a known case of ectopic left pelvic kidney and presented with chronic lower abdominal pain. Upon imaging, it was revealed that he had a staghorn stone for which he underwent laparoscopy-assisted percutaneous nephrolithotripsy (PCNL).Postoperatively, the patient underwent a quick recovery and was discharged on postoperative day 3 without any perioperative complications. Hence given our experience with this case and the similar experiences of urologists over time, the use of laparoscopy-assisted PCNL appears to create a safe way of entering the abdomen and locating the ectopic kidney as well as provide visual guidance in puncture and dilatation all the while protecting the adjacent structures from harm. This demonstrates that laparoscopy-assisted PCNL is a feasible safe and minimally invasive procedure for patients with ectopic kidneys presenting with large stones.

Testicular torsion is a relatively common urological emergency, which involves the twisting of the spermatic cord and its contents leading to ischemia to the testes, which usually presents as sudden, severe scrotal pain. In comparison, testicular neoplasms are far less commonly encountered in the emergency department as they often present as painless hard masses that grow slowly over longer periods of time. Extremely rare cases of testicular neoplasms present as sudden scrotal pain that causes a challenging task in the emergency department as physical examinations and ultrasound findings could vary and not be specific enough in confirming the diagnosis.In this case, we report a 22-year-old male who was referred from the emergency department (ED) as a case of testicular torsion from the presenting history; however, his physical examination and Doppler ultrasound findings were suspicious of testicular malignancy. The patient presented with a history of right scrotal pain for a few hours with no predisposing factors; however, examination and imaging were highly suspicious of an underlying neoplasm. The patient underwent an inguinal orchidectomy, and histology confirmed the presence of a germ cell tumor of varying components.In conclusion, a high index of suspicion for testicular torsion should always be present when a patient presents with sudden onset testicular pain; however, the differential diagnosis including testicular neoplasms should not be overlooked as it can change the management and outcome.

Renal cell carcinoma (RCC) constitutes about 2% of all adult malignancies and is the most common malignant renal neoplasm with bony metastases occurring in up to 50% of patients with RCC. In this case, we report a 42-year-old male who presented with chronic back pain and had a sudden episode of paraplegia. The patient was initially referred to the orthopedics service. He had a lumbar X-ray done followed by a CT of the spine that showed a burst fracture of the L1 vertebra with incidental finding of a right renal mass suspicious of RCC. Upon further investigations, the patient was found to have a large heterogeneous renal cortical mass with multiple cystic changes and necrosis invading the Gerota's fascia as well as a tumor thrombus extending into the right renal vein and inferior vena cava.Although it has been well established that RCC metastasizes to bones and it is not uncommon for vertebral column involvement, sudden paraplegia and incontinence resulting from lumbar fracture due to metastatic RCC has not been widely published. Conclusively, RCC is a common malignancy in which a significant number of patients have metastatic disease upon presentation and this can lead to initial confusion and delay in diagnosis, hence it should be part of the differential diagnosis when investigating chronic bony pain and pathological fractures.
