Introduction We report the experience with patients of urachal adenocarcinoma of the bladder, a rare malignancy in the urinary bladder, treated with laparoscopic partial cystectomy. Aim Solitary transitional cell carcinoma (TCC) of the dome/anterior wall of the bladder in some cases. As compared to radical surgery, partial cystectomy has a lower morbidity rate and similar oncological outcomes. We present our experience with laparoscopic partial cystectomy (LPC) in patients with urachal adenocarcinoma. Case presentation Until being admitted to the hospital, a 60-year-old woman had been suffering from painless, sporadic gross hematuria for the previous year. Her physical examination was undistinguished. Computed tomography revealed an enhancing firmly bordered mass on the anterior-superior aspect of the bladder wall. The patient then underwent cystoscopy and laparoscopic partial cystectomy simultaneously. Conclusion Based on our first experience in LPC, we suggest that cystoscopy assisted LPC is a reasonable and safe procedure with fewer complications and does not extend the operating time. The procedure's effectiveness hinges on the patient's selection. However, many cases needed to emphasize the effectiveness and safety of LPC.

Objective: To evaluate the usage of MRI in prostate cancer staging, especially in nodal involvement (N-staging) and metastasis (M-staging) of prostate cancer. Methods: This is a systematic review and meta-analysis assessing role of MRI in nodal and metastasis staging of prostate cancer. Search of studies were done through search engine using Pubmed, Cochrane, and EBSCO Host and manual searching. Quality of eligible studies were assessed using a revised version of Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) and analyzed in pooled analysis according to nodal involvement or metastasis staging, modality of diagnosis used as the index test and gold standard used using STATA version 13. Results: Total 26 studies corresponding with study’s eligibility criteria were found. Overall, usage of MRI has a sensitivity of 47% (95% CI 35% - 60%; I2 83.08%) and a specificity of 93% (95% CI 89% - 96%, I2 82.21%) in nodal involvement staging of prostate cancer, while using of MRI in M-staging of prostate cancer shows a sensitivity of 94% (95% CI 86% - 97%) and a specificity of 99% (95% CI 97% - 99%). Using lymphotrophic superparamagnetic nanoparticle (LSN) - enhanced MRI gives higher sensitivity than using MRI without LSN for N-staging of prostate cancer. Conclusion: The usage of MRI in prostate cancer staging has a moderate sensitivity and relatively high specificity in detecting lymph node. Moreover, it plays an important role and even can be used as a modality of choice in assisting bone metastatic prostate cancer detection.
