Abstract

Objectives: We present our experience with and data about a very rare neoplasm of the kidney, squamous cell carcinoma (SCC). Methods: A total of 14 patients with a diagnosis of SCC were identified on the basis of a retrospective analysis of medical records of patients who underwent surgery for renal cancers between 2015 and 2021 at the Sindh Institute of Urology and Transplantation. IBM SPSS v25 was used to record and analyze data. Results: Most patients found to have SCC of the kidney were male (71.4%). The mean (SD) patient age was 56 (13.7) years. Flank pain was the most common presenting symptom (n = 11; 78.6%) followed by fever (n = 6; 42.9%). Only 4 (28.5%) of the 14 patients had a preoperatively established diagnosis of SCC; the remaining 10 (71.4%) had an incidental finding of SCC on their histopathology specimen. The mean (SD) overall survival was 5 (4.5) months. Conclusions: SCC of the kidney is a rare upper urinary tract neoplasm reported in the literature. The gradual onset of vague symptoms, lack of pathognomonic signs, and inconclusive radiological features make the disease unsuspected in most cases, therefore delaying diagnosis and treatment. It usually presents at an advanced stage, and the prognosis is often poor. A high index of suspicion is warranted in patients with chronic kidney stone disease., Introduction Squamous cell carcinoma (SCC) of the kidney is an extremely rare neoplasm and accounts for less than 1% of all malignant renal tumors. (1-4) The gradual onset of vague [...]

Abstract

Purpose: To share our recent experience of the pattern and demography of endemic bladder calculi in children and the outcomes of current management strategies for the removal of bladder calculi in a peri-urban setting. Material and Methods: This retrospective longitudinal study was carried out at a dedicated urology centre. All patients with endemic bladder stones from January 2020 to December 2021 managed at our centre were included in this study. After discharge, each patient was followed up for 1 year. Data analysis was carried out with IBM SPSS v23. Mean and standard deviation were calculated for normally distributed continuous variables; for non-normally distributed continuous variables, median and IQR were calculated; frequency and percentage were calculated for categorical variables. Results: This study included 254 patients, with a male-to-female ratio of 10.5:1. The mean age of the patients was 4.80 ± 2.86 years. Ninety-one percent of the patients belonged to rural areas. Open cystolithotomy (OC) was performed in 11 (4.3%) patients, transurethral cystolithotripsy (TUCL) in 165 (65.0%), and percutaneous cystolithotomy (PCCL) in 78 (30.7%). The mean operative time was 48.8±4.34 minutes for TUCL, 36.18±7.4 minutes for open cystolithotomy, and 38.6±5.2 minutes for PCCL. The most common stone composition was ammonium urate + calcium phosphate (33.1%). The complication rate was 4.8% in TUCL, 12.8% in PCCL, and 27.3% in open cystolithotomy. Stone clearance was 98.1% for TUCL and 100% for both PCCL and OC. Conclusion: Paediatric bladder calculus is still endemic in rural areas of Sindh with poor socioeconomic backgrounds. Timely diagnosis and early intervention with preventive measures can lead to better outcomes and fewer complications. Minimally invasive methods of cystolithotomy have a shorter hospital stay, are more cost-effective, and have fewer complications as compared to open cystolithotomy. [ABSTRACT FROM AUTHOR]

Abstract

Renal duplexing (also known as a duplicate collection system) occurs in about 1% of children and does not usually require medical attention. The condition results in two tubes rather than the normal single ureter tube for each kidney. Medical problems that warrant attention are obstruction of urine flow or the backflow of urine into the kidney (reflux). These double ureter tubes can join in a "y" shape before reaching the bladder (partial duplex) and combining their urine delivery. In other cases, each duplicate ureter empties into the bladder on its own (complete duplex). There is cause for concern when a duplex kidney is associated with urological conditions requiring treatment. Renal duplexing can cause urine to reflux into the kidney (vesicoureteral reflux) rather than going into the bladder and can cause subsequent Urinary Tract Infection (UTI). This can result in serious consequences like the loss of renal parenchyma (reflux nephropathy) and sometimes death in acute infections if not attended to in a timely manner. Weigert-Meyer postulated that rule i-e in a complete duplex system is mostly associated with reflux in lower moiety and obstruction in upper moiety with ectopic insertion and ureterocele. Ureteroceles may require simple management of symptoms or surgery, depending on the size of the ballooning, the functioning of the kidney and bladder and the degree of urine obstruction. An ectopic ureter is when the ureter opens and drains urine outside the bladder rather than inside.
