RESUMO
BACKGROUND: Emphysematous pyelonephritis (EP) is a severe necrotizing infection of the renal parenchyma which is associated with significant case mortality. We sought to identify the incidence and predictive risk factors associated with EP mortality. METHODS: Two electronic databases, PubMed and Web of Science, were searched from their inception until June 06, 2021 for relevant articles. Two independent teams reviewed abstracts and extracted data from the selected manuscripts. A meta-analysis has been reported in line with PRISMA 2020 and AMSTAR Guidelines. RESULTS: Of the 1080 retrieved abstracts, 79 underwent full-text review and 45 studies were included in the final analysis, comprising a total cohort of 1303 patients and 177 mortalities. The pooled prevalence of mortality among the patients with EP disease was 13%. Our analysis found a significantly decreasing trend in mortality rates, an increasing trend in minimally invasive intervention and decreasing trends in emergency nephrectomy in the EP studies from 1985 to 2020. Significant risk factors that were associated with a negative impact on survival of EP patients included sepsis (OR = 15.99), shock (OR = 15.57), disturbance of consciousness (OR = 12.11), thrombocytopenia (OR 7.85), acute renal failure (OR = 5.41), Wan classification I (OR = 4.57), emergency nephrectomy (OR = 3.73), Huang-Tseng classification III-IV (OR = 2.4) and medical management alone (OR = 2.04). Female sex (OR = 0.52) and minimally invasive intervention (OR = 0.47) (percutaneous nephrostomy or ureteral stent placement) were associated with decreased mortality rates. CONCLUSIONS: Our study results demonstrated several significant risk factors that could help guide treatment to reduce the mortality risk of EP patients. Clinically, early treatment with a combination of minimally invasive intervention and appropriate medical management may be protective for reducing mortality risk in EP patients.

Introduction: Radical cystectomy combined with orthotopic urinary diversion is a chosen approach for treating invasive bladder cancer. However, urothelial cell carcinoma is characterized by its potential for recurrence and the development of multiple tumors in the urinary tracts. In the natural progression of transitional cell carcinoma, the remaining ureteral stump is considered a predicted site for possible recurrence after radical cystectomy. Currently, there is no specific recommendation for the diagnosis and management of this condition. Objective: We report a rare case in a 74-year-old male patient who was diagnosed with anterior urethral carcinoma following a history of radical cystectomy and Hautmann ileal neobladder reconstruction. Additionally, we summarize some novel findings regarding risk factors, diagnosis, treatment, and prognosis in patients with recurrent bladder cancer in the urethra after radical cystectomy. Methods: A case report and mini review. Results: The patient was diagnosed with recurrent bladder cancer in the urethral after radical cystectomy using magnetic resonance imaging of the pelvis, cystoscopy, and biopsy. Complete urethrectomy and creation of a permanent percutaneous urinary diversion were performed. No intraoperative or postoperative complications were recorded. The patient was discharged 3 days after the surgery. Conclusion: Urethral cancer following radical cystectomy for bladder cancer treatment is a rare condition. Risk factors for this occurrence include male gender, non-use of orthotopic neobladder reconstruction technique, invasive tumors in the prostatic urethra, and multifocal tumors. The treatment of these tumors can be determined based on the extent of invasion and histological characteristics, leading to the choice between radical urethrectomy or alternative conservative treatments.
RESUMO
BACKGROUND: The duplex kidney is one of the common congenital anomalies of the kidney and urinary tract. We present two cases of renal tumor accompanied with ipsilateral duplex kidney. The image of the tumor, renal artery system and collecting system were rendered by AI software (Fujifilm's Synapse® AI Platform) to support the diagnosis and surgical planning. CASE PRESENTATION: Two Vietnamese patients (a 45-year-old man and a 54-year-old woman) with incidental cT1 renal cell carcinoma (RCC) were confirmed to have ipsilateral duplex kidneys by 3D reconstruction AI technique. One patient had a Renal score 9ah tumor of left kidney while the other had a Renal score 9 × tumor of right kidney in which a preoperative CT scan failed to identify a diagnosis of duplex kidney. Using the Da Vinci platform, we successfully performed robotic partial nephrectomy without any damage to the collecting system in both cases. CONCLUSION: RCC with duplex kidneys is a rare condition. By utilizing a novel AI reconstruction technique with adequate information, two patients with RCC in duplex kidneys were successfully performed robotic partial nephrectomy without complication.

Objective: To compare the perioperative, oncological, and functional outcomes between single-port robot-assisted radical prostatectomy (SP-RARP) and multiport robot-assisted radical prostatectomy (MP-RARP) via a meta-analysis. Methods: For relevant articles, three electronic databases, including PubMed, Scopus, and Web of Science, were searched from their inception until January 15, 2022. A meta-analysis has been reported in line with PRISMA 2020 and AMSTAR Guidelines. The risk ratio and weighted mean difference (MD) were applied for the comparison of dichotomous and continuous variables with 95% confidence intervals (CI). Results: Of the 368 retrieved abstracts, 41 underwent full-text review, and seven studies were included in the final analysis, comprising a total cohort of 1,934 cases of RARP (355 SP-RARP cases and 1,579 MP-RARP cases). Compared to MP-RARP, the SP-RARP group had less postoperative pain score (MD = -0.7, 95% CI -1 to -0.4, P<0.001), morphine milligram equivalents usage (MD = -3.8, 95% CI -7.5 to -0.1, P=0.04), hospital stay (MD = -1, 95% CI -1.8 to -0.1, P=0.019), and urinary catheterization time (MD = -1.1, 95% CI -1.9 to -0.3, P=0.008). However, the SP-RARP group had a longer console time than the MP-RARP group (MD = 5.3, 95% CI 2.6 to 7.9, P<0.001). Conclusions: Our study demonstrated that early results were mostly equivalent with the single-port approach. This technology may help to reduce the hospital stay and postoperative pain for patients undergoing radical prostatectomy compared to MP-RARP, without compromising the functional and early oncological outcomes.
RESUMO
INTRODUCTION: In this case report, we demonstrate our technique of a retroperitoneal laparoscopic heminephrectomy for a T1b right hilar tumor in a horseshoe kidney. CASE PRESENTATION: A 77-year-old Vietnamese woman presented to the hospital because of right flank pain. On presentation, her serum creatinine was 0.86 mg/dL and glomerular filtration rate was 65.2 mL/minute/1.73 m2. According to her renal scintigraphy, glomerular filtration rates of the right and left moieties were 24.2 and 35.5 mL/minute, respectively. Computed tomography imaging demonstrated a 5.5 × 5.0 cm solid hilar mass with a cT1bN0M0 tumor stage was in the right moiety. After discussion, the patient elected a minimally invasive surgery to treat her malignancy. The patient was placed in a flank position. We used Gaur's balloon technique to create the retroperitoneal working space, and four trocar ports were planned for operation. Three arteries were dissected, including two arteries feeding the right moiety, one artery feeding the isthmus, and one vein, which was clipped and divided by Hem-o-lok. The isthmusectomy was performed with an Endostapler. Consequently, the ureter was clipped and divided. Finally, the whole right segment of the horseshoe kidney was mobilized and taken out via the flank incision. RESULTS: The total operative time was 250 min with an estimated blood loss of 200 mL. The patient's serum creatinine after surgery was 1.08 mg/dL, and glomerular filtration rate was 49.47 mL/minute/1.73 m2. The patient was discharged on postoperative day #4 without complication. Final pathologic examination of the tumor specimen revealed a Fuhrman grade II clear cell renal cell carcinoma, capsular invasion, with negative surgical margins. After a three-month follow-up, the serum creatinine was 0.95 mg/dL, and glomerular filtration rate was 57.7 mL/minute/1.73 m2. Local recurrence or metastasis was not detected by follow-up computed tomography imaging. CONCLUSIONS: Retroperitoneal laparoscopic heminephrectomy is a safe and feasible technique for patients with renal cell carcinoma in a horseshoe kidney and may be particularly useful in low income settings without access to robotic technology.

BACKGROUND: Penile strangulation is an uncommon urological emergency that requires prompt intervention to avoid potentially serious sequelae including loss of the distal penis secondary to ischemia and subsequent gangrene. We present a case report of a patient who presented to the hospital with penile strangulation injury of 10-hour duration secondary to the presence of a thick hexagonal steel nut. This case is presented in accordance with Consensus Surgical Case Report guidelines. CASE PRESENTATION: A 24-year-old Vietnamese man presented to the emergency room with urinary retention and decreased penile sensation following a 10-hour history of penile strangulation due to the presence of a thick hexagonal steel nut that he had placed around the shaft of the penis for the purpose of sexual enhancement during masturbation. The hexagonal nut was tightly entrapping the penile shaft, resulting in edema, congestion, and swelling of the distal 5 cm of the phallus. Given the thickness of the foreign body as well as the degree of penile swelling, we were unable to remove the hexagonal nut using traditional methods of alleviating penile strangulation injuries. Following consultation with a dental colleague, a dental diamond drill handpiece was utilized to cut the foreign body without injury to the underlying penile skin. Subsequent follow-up in clinic demonstrated no significant urinary or sexual sequalae from this episode. CONCLUSION: We report a case of penile strangulation requiring novel instrumentation and collaboration for successful treatment.

OBJECTIVES: To assess the safety and efficacy of introducing robotic-assisted laparoscopic donor nephrectomy (RALDN) to the standard retroperitoneal endoscopic donor nephrectomy (REDN). METHODS: Data were collected prospectively from 124 consecutive living kidney donors (93 for REDN subgroup and 31 for RALDN subgroup) from February 2018 to December 2020. Donor baseline demographics, perioperative outcomes and recipient outcomes were recorded, and these parameters were compared between the two subgroups before and after propensity-score matching. RESULTS: Mean age was 51.1 ± 9.1 years; 42.7% were males; mean body mass index was 22.7 ± 2.4; and there were 109 (88%) left kidneys. The following data of REDN and RALDN was, respectively, recorded: operative time (213 ± 43 versus 216 ± 39 min, p = 0.721), warm ischemic time (4.7 ± 1.2 versus 4.9 ± 1.4 min, p = 0.399), postoperative complications (5.4% versus 6.5%, p = 1), haemoglobin (g/L) drop (9.4 ± 7.2 versus 9.7 ± 6.6, p = 0.836), blood creatinine at 6 month (1.15 ± 0.23 versus 1.13 ± 0.24 mg/dL, p = 0.734) and at 1 year (1.09 ± 0.22 versus 1.17 ± 0.28 mg/dL, p = 0.591). In post-propensity score matched analyses, there was no significant differences between the two groups including intraoperative and postoperative complications. CONCLUSIONS: RALDN could be safely introduced into a living donor program experienced in laparoscopic donor nephrectomy. The outcomes of our study comparing these minimally invasive techniques are mostly similar in terms of intraoperative and postoperative outcomes for kidney donors.
