RESUMO
PURPOSE: We report our experience with transperitoneal laparoscopic nephrectomy (LN) for giant hydronephrosis (GH) and compare the outcome data with open nephrectomy (ON). PATIENTS AND METHODS: The retrospective data of 88 patients (52 males and 36 females) who underwent LN or ON for treatment of GH in the period between October 2015 and December 2019 were investigated. LN was performed in 38 patients, while 50 patients underwent ON. We compared the two groups for success, operative time, and intraoperative and postoperative complications. RESULTS: The mean age of the patients in the LN group was 45.8 ± 11.4 years, and it was 44.7 ± 10.8 years in the ON group. The mean operative time in the LN group was statistically significantly longer when compared with the ON group195 ± 18 min versus 127 ± 22 min (p = 0.01).The estimated blood loss was significantly greater in the ON group (p = 0.01). However, no patients required blood transfusions in either group. The visual analog pain (VAP) scores were significantly higher on both day 1 and day 2 in the ON group 3.6 ± 0.9 and 2 ± 0.7 versus 2.7 ± 0.6 and 1.4 ± 0.5 in LN group, (p = 0.01). CONCLUSION: LN for GH is feasible, safe, and efficacious. Compared to open surgery, the laparoscopic approach resulted in significantly shorter hospital stays, decreased morbidity, and quicker recovery. Some tips and tricks could help to do it in an easier way and reduce the operative time.

This study aimed to compare the expression of genes regulating follicles development, survival and steroid hormones secretion in oocytes and granulosa cells (GCs) and study the correlation between their expression and follicular fluid (FF) levels of progesterone (P4) in pregnant and non-pregnant camels. In total, 138 ovarian pairs from slaughtered camels were used. Gene expression and hormonal assay were determined using real-time polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA), respectively. The obtained results revealed that the number of follicles (3-8 mm) was significantly (P < 0.05) lower in pregnant, compared with non-pregnant, camels. P4 level in the FF was significantly (P < 0.05) higher in pregnant, compared with non-pregnant, camels. However, no significant (P > 0.05) difference was noticed in the oestradiol (E2) level. STAR, PTEN, IGF1 and BCL2 mRNA levels were significantly higher in GCs and significantly lower in oocytes of pregnant, compared with non-pregnant, camels. However, follicle-stimulating hormone receptor (FSHR) mRNA level was significantly lower in GCs and oocytes, and the BMP15 mRNA level was significantly lower in oocytes of pregnant, compared with non-pregnant, camels. P4 level in FF was positively correlated with STAR, PTEN, IGF1 and BCL2 mRNA levels in GCs and negatively correlated with BMP15 mRNA levels in oocytes and FSHR mRNA levels in GCs and oocytes of pregnant camels. It could be concluded that pregnancy-induced variations in oocytes and GC expression of BMP15, IGF1, FSHR, STAR, BCL2, and PTEN genes might be associated with a decrease in the number of follicles and an increase in the FF level of P4.

Purpose: Extracorporeal shockwave lithotripsy (SWL) results in a lower stone-free rate (SFR) for ectopic kidneys when using the standard technique, directing the shock wave from the same side of the stone; however, this may not be the optimal approach when the ectopic kidney is located more medial and anterior than the normally positioned kidney. Thus, contralateral coupling where waves come from the opposite direction may result in a better outcome. We tested the feasibility and outcome of contralateral coupling during SWL for stone in ectopic kidney. Materials and Methods: We prospectively recruited 20 patients with simple renal ectopia, who presented with renal stones that were amenable for SWL in the period between 2014 and 2018 at outpatient clinic of urology department, Minia University. Patients received SWL in Private Nile SWL Center were included to benefit from the ability of the electromagnetic SWL lithotripter. We did SWL in a supine position, and then contralateral coupling was performed from the opposite side of the affected kidney, rather than using the standard ipsilateral coupling approach. The SFR and various pre-, intra-, and postprocedural SWL variables were assessed, including stone characteristics, body habitus, shock wave numbers, and auxiliary measures. Count and percentages were calculated. Results: The mean stone radius was 14.7 mm with a mean S.T.O.N.E. (size, topography, obstructions, number of stones, and evaluation of HUs) of 9.6 points. Effective SWL was achieved in 80% of cases, 65% of them were stone free with effective single SWL session in 56% of cases. Hematuria, infection, and obstruction occurred in 50%, 20%, and 15% cases, respectively. One case required ureteral stent insertion. Conclusions: SWL applied through contralateral coupling is feasible, with comparable safety profile to the standard ipsilateral approach. Better SFR was achieved with the contralateral approach, in fewer sessions. However, the recruitment of more cases is necessary.

INTRODUCTION: Although it is apparently simpler to perform unstented tubularized incised plate (TIP) repair for distal hypospadias repair, consensus on feasibility of the use of unstented repair is still a matter of debate. Evidence reporting that unstented repair outcome is comparable to stented repair, especially in the long-term, is still weak due to reporting outcome inconsistencies, different study designs, inclusion of more than one technique, and inherent variability in meatal locations. Thus, we need a continuous and evolving assessment of the outcome of unstented repair to compile adequate evidence on the advantage of unstented TIP repair in distal hypospadias entity. The aim of this article was to review our long-term results with tubularized incised plate urethroplasty for distal hypospadias repair without a postoperative stent to determine its outcome which might justify its use. MATERIAL AND METHODS: After a review of 154 patients with distal penile hypospadias, who underwent repair in Minia Urology & Nephrology University Hospital in the period between June 2015 and February 2018, we excluded cases who underwent MAGPI repair, redo cases and patients who failed to complete follow-up. We chose 72 patients who had only 1st time TIP repair and whom we could contact. A total of 44 out of 72 cases with stented repair were assigned to Group A, while 28 cases with unstented repair were assigned to Group B. Success was assessed based on Hypospadias Objective Penile Evaluation (HOPE) score by three separate senior pediatric urology consultants, independent of the surgeon and in the absence of high post-void residual urine (PVR). Average rate was calculated to be compared between both study groups. RESULTS: There was no statistically significant difference regarding preoperative meatal location and age at repair and short-term complications. In the long-term; there was no statistically significant difference between the occurrence of urethrocutanous fistula (UCF, 4 vs 2 cases in Group A & B, respectively) and complete disruption (2 cases in each group) with need for redo repair. Results of total mean of HOPE score calculated showed no statistically significant differences between study groups and also failed to showed statistical significance on individual domains of HOPE score. CONCLUSIONS: Unstented TIP repair showed a similar outcome to stented TIP repair of distal hypospadias especially in the long-term despite a more troublesome early postoperative period.
RESUMO
BACKGROUND: Results of SWL in treatment of upper ureteral calculi are conflicting which is definitely affected by stone locations along the proximal ureter, which is may be due to the more deep and medial course of the ureter distally over the thick and strong abdominal back wall which may hinder shock waves. METHODOLOGY: One hundred patients with radiopaque proximal ureteral stone opposite 4th and 5th lumbar vertebrae who had SWL were randomized into two groups. First group had SWL through anterior belly wall in supine position with countertraction, the second group had standard posterior SWL. Patient's demographics and stone characters were evaluated assessing stone burden and calculating S.T.O.N.E score. Patients were followed up to assess stone-free rate using serial digital plain X-ray KUB. RESULTS: Anterior approach needed less power to reach SFR (p = 0.05) in less number of sessions where 90% of cases in anterior group had only one session to reach SFR versus 52% in posterior group (p = 0.001). Also, post-SWL pain, hematuria, obstruction and infection were significantly less in anterior group (p = 0.005). Although patients who had anterior approach showed statistically significant shorter time to stone expulsion. SFR does not differed significantly between study groups (p = 0.02). On further analysis; anterior SWL had a better chance to reach SFR (HR = 1.6, p = 0.001). CONCLUSION: It seems that anterior SWL approach in supine position is safe and effective especially in mild obese patient with floppy abdomen. Patients who had anterior SWL approach had a better chance to achieve stone-free rate.

Much is still unknown about LUT function after receiving renal graft. Graft function was the main focus of different studies discussing the same issue. However, these studies ignored the effects of the graft on lower tract function and more demand for bladder cycling and growth of the child. Therefore, we aimed at evaluating the LUT function after RT into patients with LUTD. We enrolled a retrospective cohort of 83 live renal transplant children with LUTD. The 44 patients in Group (A) had a defunctionalized bladder, and the 39 patients in Group (B) had underlying LUT pathology. All patients had clinical and urodynamic evaluation of LUT functions at least 1 year after RT. We found that the improvement in patients with impaired bladder compliance was 73% in Group (A) and 60% in Group (B), with no statistically significant difference between the study groups. In Group (B), there was statistically significant worsening of MFP (8.4%) and mean PVR (79.9%) after RT. In Group (A), mild but stable significant improvement of all clinical and urodynamic parameters was observed. Serum creatinine was significantly worse in patients with pathological LUTD compared with those with defunctionalized bladder but without significant effect on graft survival. All LUT variables seemed to have no adverse effect on graft survival except for use of CIC and augmented bladder. Incident UTI independent of LUT variables accounted for 20% of graft creatinine change.

Hepatocellular carcinoma (HCC) is a primary liver malignancy, and is now the six most common in between malignancies. Early diagnosis of HCC with prompt treatment increases the opportunity of patients to survive. With the advances in understanding the molecular biology of HCC, new therapeutic strategies to treat HCC have emerged. There is a growing consensus that vitamins are important for the control of various cancers. Biochemical evidence clearly indicates that HCC cells are responsive to the inhibitory effect of vitamin D, vitamin D analogues and vitamin K. In this review, we summarize the mechanisms used by vitamin D and K to influence the development of HCC and the latest development of vitamin analogues for potential HCC therapy.
