RESUMEN
OBJECTIVE: To determine the frequency of adrenal gland involvement (AGI) in patients with renal cell carcinoma (RCC) and assess the ability of preoperative computed tomography (CT) imaging to predict AGI prior to radical nephrectomy (RN). METHODS: We retrospectively identified 90 patients who underwent RN with concomitant ipsilateral adrenalectomy (CIA) between 2019 and 2021 at our institution. We reviewed the preoperative CT findings and final pathology reports to assess AGI and determine the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of preoperative CT imaging. RESULTS: Five patients (5.5%) had AGI on pathological analysis. On preoperative CT, eight patients had CT findings suspicious of AGI. All five patients with pathological AGI were identified preoperatively yielding a sensitivity of 100%. Pathological analysis in all patients who did not demonstrate AGI on imaging showed no adrenal invasion, yielding a negative predictive value of 100%. High-grade tumors were significantly associated with AGI (84.4% vs. 33.6%, p = 0.02). Patients with AGI had larger tumor size when compared with those without AGI on final pathology (10 cm vs. 6.89 cm, p = 0.07). CONCLUSIONS: The overall incidence of AGI in patients with RCC is low. Preoperative CT can accurately identify those with AGI and can thus prevent unnecessary CIA during RN.
RESUMEN
OBJECTIVE: To introduce the Penile Trauma Score (PTS), a new statistically driven classification system aimed at enhancing the management of penile trauma by providing clinically relevant treatment protocols. METHODS: A retrospective review was conducted of 34 men with penetrating penile injuries at the Elvis Presley Level 1 Trauma Center, Memphis, from January 2014 to December 2016. Variables assessed included injury mechanism, location, depth, and follow-up outcomes related to voiding and erectile function. Odds ratios were calculated using superficial penile injury as the control group. RESULTS: Based on physical examination findings and odds ratios calculated, the PTS was developed. Results indicated that higher PTS scores necessitated surgical intervention, while lower scores could be managed nonoperatively. Follow-up showed no missed injuries or reported dysfunctions, validating the PTS's effectiveness. CONCLUSION: The PTS represents an important modification in the classification and management of penile trauma. By integrating practical, easily identifiable injury characteristics, the PTS facilitates more streamlined surgical decision-making and potentially reduces unnecessary diagnostic procedures. However, further prospective studies with larger sample sizes and longer follow-up are needed to fully validate the PTS's clinical utility.
RESUMEN
PURPOSE: Vacuum-assisted mini-percutaneous nephrolithotomy (vmPCNL) is being increasingly adopted due to its faster operating times and lower incidence of postoperative infectious complications (IC), however, studies have been limited by small sample sizes. We hypothesize that vmPCNL is an efficacious treatment for renal stone disease with acceptable stone-free rates (SFR) and low incidence of IC. The objectives of this study were to measure SFR three months after surgery, determine the factors influencing SFR, and determine the rates of postoperative IC after vmPCNL. MATERIALS AND METHODS: Seven hundred and sixty seven patients underwent vmPCNL for the treatment of renal stones > 20 mm at a single institution. Patients underwent postoperative computed tomography at three months to assess SFR. Postoperative fever and SIRS/Sepsis were recorded for individual patients. Multivariate logistics regression was performed to assess predictors of SFR. RESULTS: The SFR was found to be 73.7% at three months. Stone burden (OR 0.39, 95% CI [0.33-0.46]) and age (OR 1.03, 95% CI [1.01-1.04]) emerged as statistically significant predictors of SFR on multivariate analysis. 5.5% of patients experienced postoperative fever, while 2.9% experienced SIRS/Sepsis. CONCLUSIONS: This is the largest continuous cohort of patients to undergo vmPCNL for stone disease and demonstrates that vmPCNL is safe and efficacious, with an SFR of 74% at three months. The incidence of postoperative fever and SIRS/Sepsis is 5.5% and 2.9% respectively. Further randomized studies with large sample sizes are required to ascertain the rates of these complications in comparison to conventional approaches.
RESUMEN
PURPOSE: Precision Prostatectomy (PP) is a viable treatment option for men with unilateral dominant cancer who are interested in preserving functional outcomes. To date, the data published about the outcomes of this technique has come from a single center only (Henry Ford - HF). We present the surgical, functional, and oncological outcomes of the first series of patients to undergo PP outside of HF, to demonstrate the safety and reproducibility of the technique. METHODS: Between 2022 and 2023, PP was offered to select patients who were interested in preserving their functional status. Men who underwent PP were followed at 3 monthly intervals; information regarding their functional status was simultaneously obtained. Men who had biochemical recurrence were advised to undergo remnant biopsy. If residual cancer was detected, then remnant removal was performed. RESULTS: The median age and median PSA of the study group was 63 years and 6.89 ng/ml respectively. The median operative and console times were 196.5 and 154 minutes. No intra-operative complications were noted. Three patients had a total of three post-operative complications. Three patients had biochemical recurrence; cancer was not detected in any of these patients on postoperative biopsies of the prostatic remnant. At 12 months, 91% of patients reported using 0 pads/day and 90.9% of pre-operatively potent patients were potent at 12 months. CONCLUSION: PP is a safe and reproducible technique that can ensure cancer control and preservation of functional status in select patients. Further studies with large sample sizes and longer follow-up are required to ascertain the long-term outcomes of this surgical technique.
