Optimal outcomes after radical prostatectomy can be achieved in a small majority of cases. Time to full recovery is primarily dictated by recovery of erectile function. This information is helpful for patients interested in their chances of returning to their preoperative functional state.
A careful analysis of 54 patients with a solitary kidney and who had a partial nephrectomy is reported by authors from New York. They found it to be a safe procedure with an acceptable decline in renal function which stabilised during the first year. The requirement for temporary haemodialysis was low.
Authors from China report on the use of a retroperitoneoscopic approach to subcapsular nephrectomy in patients with infective or adhesive non‐functioning kidneys. Their results were excellent and they showed this to be an acceptable technique, with minimal trauma and blood loss and a quick recovery.
OBJECTIVE
To report the experience of partial nephrectomy in patients with a solitary kidney at one institution, with analysis of renal function, complications, oncological efficacy and survival.
PATIENTS AND METHODS
We identified 54 consecutive patients with a solitary kidney who had a partial nephrectomy between December 1989 and July 2003. Variables examined included patient age and gender, renal function, renal ischaemia time, surgical margin status and complications. Pathological features, e.g. tumour size, histological subtype and tumour stage, were also assessed. Disease‐free probability and overall and cancer‐specific survivals were determined.
RESULTS
The histological subtype was clear cell in 35 cases (65%), papillary in 10 (19%), oncocytoma in four (7%), chromophobe in two (4%), unclassified in one (2%) and multiple subtypes in two (2%). The median creatinine level before surgery was 14 mg/L, which increased to 16 mg/L 6 months afterward, and at 1 and 2 years after surgery it was 15 mg/L. Two patients developed end‐stage renal disease requiring haemodialysis, one soon after surgery and another 8 years after nephron‐sparing surgery. In all, 26% of patients developed at least one perioperative complication, with acute renal failure and urinary fistula being the most common. At 5 years the overall and cancer‐specific survival, and disease‐free probability were 68%, 88% and 73%, respectively.
CONCLUSIONS
Partial nephrectomy is safe in patients with a solitary kidney, with an acceptable decline in renal function and low likelihood of requiring temporary or permanent haemodialysis. After an initial decline, renal function appears to stabilize during the first year.
Quality assurance efforts through pathological and intraoperative documentation review can help decrease the positive margin rate, particularly in organ confined disease. However, eradicating positive margins at the distal prostatic apex remains a challenge.
Introduction: The role of magnetic resonance imaging (MRI)-fusion biopsy (FB) remains unclear in men with prior negative prostate biopsies. This study aimed to compare the diagnostic accuracy of FB with concurrent systematic biopsy (SB) in patients requiring repeat prostate biopsies.
Methods: Patients with previous negative prostate biopsies requiring repeat biopsies were included. Those without suspicious lesions (≥Prostate Imaging Reporting and Data System [PI-RADS] 3) on MRI were excluded. All patients underwent FB followed by SB. The primary outcome was the sensitivity for clinically significant prostate cancer (Gleason score ≥7). The secondary objective was identification of potential predictive factors of biopsy performance.
Results: A total of 53 patients were included; 41 (77%) patients were found to have clinically significant prostate cancer. FB had a higher detection rate of significant cancer compared to SB (85% vs. 76%, respectively, p=0.20) and lower diagnosis of indolent (Gleason score 3+3=6) cancer (10% vs. 27%, respectively, p=0.05). FB alone missed six (15%) clinically significant cancers, compared to 10 (24%) with SB. SB performance was significantly impaired in patients with anterior lesions and high prostate volumes (p<0.05). There was high degree of pathological discordance between the two approaches, with concordance seen in only 34% of patients.
Conclusions: In patients with prior negative biopsies and ongoing suspicion for prostate cancer, a combined approach of FB with SB is needed for optimal detection and risk classification of clinically significant disease. Anterior tumors and large prostates were significant predictors of poor SB performance and an MRI-fusion alone approach in these settings could be considered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
